SUMMARY:The 19th Seminar on Commutative Algebra and related topics
DESCRIPTION:Every year the school of mathematics of IPM-Tehran organizes a seminar and workshop to introduce the research topics in the main streams of “Algebraic Geometry\, Commutative algebra and Combinatorial commutative algebra” to young researchers and PhD students\, and encourage them to collaborate in teams led by well-known mathematicians in this area. This year we have paid special attention to inviting regional speakers\, as well as international leaders. Our list of speakers highlights female mathematicians\, and the areas represented are those in which there is regional expertise\, hopefully leading to new collaborations.\nThe conference is preceded by a workshop on Lefschetz properties and connections to algebra\, geometry and combinatorics. The workshop will feature the leading questions in the area\, and the lectures will be delivered by some of the main players in this field.

SUMMARY:Atlantic Graph Theory Seminar: Sebastian Cioaba\, University of Delaware
DESCRIPTION:Addressing graphs and hypergraphs \nIn 1970s\, Ron Graham and Henry Pollak introduced the notion of graph addressing which is a labeling of the vertices of an undirected graph by words of the same length over the alphabet {0\,1\,*} such that the distance between any two vertices equals the number of positions in their labels/addresses where one vertex has a 0 and the other one has a 1. The minimum of length of such words has been investigated by various people and is closely related to the partition of the edge set of the graph into bicliques (complete bipartite subgraphs). In this talk\, I will describe some recent results related to this parameter for various families of graphs and the corresponding problem for hypergraphs. \nZoom info:\n\nhttps://us02web.zoom.us/j/87564743456?pwd=cTdkMGxYQ0dGaG4zdkZpeFVlTmsrQT09 \nMeeting ID: 875 6474 3456\nPasscode: 259500

SUMMARY:Symmetry\, Invariants\, and their Applications: A Celebration of Peter Olver’s 70th Birthday
DESCRIPTION:This is a proposal for a workshop on symmetry\, invariants\, and their applications in celebration of Peter Olver’s 70th birthday. Transformation and groups are an omnipresent concept in nature\, science\, and art. Many biological\, chemical\, physical\, or man-made structures exhibit symmetries as a fundamental design principle or as an essential aspect of their functioning. Symmetry groups also occur in a wide variety of modern applications including computer vision\, archaeology\, numerical integration\, and neural networks\, differential equations\, geometry\, and applied mathematics. \nDuring his prolific career\, Peter J. Olver played an important role in the development of symmetry group methods to differential equations\, geometry\, and applied mathematics.The purpose of the workshop is to bring together leading experts\, promising younger researchers\, and graduate students from around the world to assess the rapid advances occurring in the field of symmetries and invariants\, and to evaluate the most promising directions of future developments.

SUMMARY:AARMS Geophysical Inverse Problems Discussion
DESCRIPTION:Lelièvre et al.\, 2012\, Joint inversion of seismic traveltimes and gravity data on unstructured grids with application to mineral exploration.\nhttps://library.seg.org/doi/10.1190/geo2011-0154.1\n\nIf you are unable to access the paper through that link\, please email the organizer (and co-author on the paper) for a copy (plelievre@mta.ca).\nThis paper looks at various different methods to enforce the similarity of the different models in a joint inversion. This paper will help us discuss previous themes in relation to joint inversion\, including the deterioration of numerical behavior for particular objective functions\, constructing piecewise-constant models\, and determining the value of the regularization parameter(s).\n\nFriday\, July 29\, 2022 @ 1:30 pm – 2:30 pm (Atlantic time)\n\nConnection details will be published on the organizer’s website:\nhttps://www.esd.mun.ca/~peter/AARMS-CRG.html

SUMMARY:AARMS Geophysical Inverse Problems Discussion
DESCRIPTION:Friday\, July 15\, 2022 @ 1:30 pm – 2:30 pm (Atlantic time) \nBijani et al.\, 2017\, Physical-property-\, lithology- and surface-geometry-based joint inversion using Pareto Multi-Objective Global Optimization.  \nIf you are unable to access the paper through that link\, please email the organizer (and co-author on the paper) for a copy (plelievre@mta.ca). \nThis paper introduces the concept of multi-objective optimization and Pareto-optimality. In this work\, instead of attempting to select a single value for the regularization parameter\, the methods sample the entire Pareto-curve (Tikhonov curve)\, or for more than two objective functions the Pareto-(hyper)surface. The challenge is then deciding how to visualize and otherwise explore all the possible models provided\, extract useful information from them\, and make reasonable interpretations. \nConnection details will be available on the organizer’s website.

SUMMARY:Canadian Undergraduate Mathematics Conference / Congrès canadien des étudiant(e)s en mathématiques
DESCRIPTION:The Canadian Undergraduate Mathematics Conference (CUMC) is a national conference organized each summer by undergraduate students for undergraduate students at different institutions across Canada. \nThe CUMC is an opportunity for students to explore mathematics outside their usual surroundings and spark their interest in areas they have not yet been exposed to. Indeed\, the core of the gathering consists of a series of talks given by participants. The conference therefore provides a unique chance for students to present what they find most fascinating and exciting\, as well as to practice their expository skills in an inclusive and noncompetitive environment. As a national conference\, the CUMC is a bilingual event. Moreover\, the event seeks to promote diversity within the field of mathematics itself\, by offering keynote lectures in both pure and applied fields. \nThe CUMC is primarily organised by a local organising committee at the host institution\, under the aegis of Studc.

SUMMARY:Computational Aspects in Finance and Actuarial Sciences
DESCRIPTION:The AARMS CRG Conference on Computational Aspects in Finance and Actuarial Sciences will be held July 8-9  in PEI\, Canada. This conference is mainly hosted by the Atlantic Association for Research in Mathematical Sciences (AARMS) collaborative research group (CRG) and the School of Mathematical and Computational Sciences (SMCS) at University of Prince Edward Island (UPEI)\, Canada\, and is a unique venue that brings together leaders in finance\, and actuarial sciences\, across disciplines\, and across borders\, tackling very important and timely topics in finance and actuarial sciences. Our intention for this conference is to have a broad scope in terms of applications in Finance and Actuarial Sciences but we would like to put emphasis on numerical and computational issues (including trendy topics such as machine learning algorithms in finance and insurance\, but also more traditional methods such as numerical solutions for PDEs\, Monte Carlo simulations\, etc). The conference will include a dynamic program with high quality speakers focusing on innovative research\, policy discussions\, and business challenges and successes. \nZOOM link:  https://us06web.zoom.us/u/kUOl82t1s

DESCRIPTION:Dr. Ivan Shestakov will be visiting St. John’s\, NL\, from May 29 to June 3\, as a guest of the Atlantic Algebra Centre in the department of Mathematics and Statistics at Memorial University and as an AARMS Distinguished Lecturer.  While there\, Dr. Shestakov will give a plenary talk to the International Workshop “Groups\, Rings\, Lie and Hopf Algebras IV”. The title of the talk is “Non-matrix Varieties and Coordinatization Theorems”.  Dr. Shestakov will also deliver a public lecture as described below. \nTame and Wild Automorphisms of Free Algebras \nThe notion of automorphism captures the idea of symmetry in mathematics. More precisely\, an automorphism of an object is an invertible transformation that preserves the object’s structure. Many important objects in algebra possess natural examples of such transformations\, which are referred to as elementary automorphisms. For such an object\, an automorphism is called tame if it can be represented as a composition of elementary automorphisms\, otherwise it is called wild. \nIt is known that the automorphisms of polynomial algebra and of free associative algebra are tame in case of two generators while in case of three generators there exist wild automorphisms. \nIn our talk\, we will discuss known results and open problems on tame and wild automorphisms in various classes of algebras. \nSpeaker Bio \nIvan Shestakov was born on August 13\, 1947\, in Zaval’\, Irkutsk region\, Russia. After graduating from the Physical-Mathematical School in Novosibirsk\, he entered Novosibirsk University in 1965. There he obtained his first results in algebra\, under the guidance of professors K. Zhevlakov and A. Shirshov. His Masters thesis “On a Class of Non-commutative Jordan Rings” was awarded the Medal of the Academy of Sciences of USSR for students. In 1970 Shestakov graduated from Novosibirsk University and entered as a researcher the Sobolev Institute of Mathematics. In 1973 he received his Ph.D. from Novosibirsk University\, and in 1978 he earned the Doctor of Sciences from the Sobolev Institute of Mathematics for the work “Free Alternative Algebras”. In 1974 Shestakov became a professor of the Novosibirsk State University. Since 1999 he has held a position of Full Professor at the University of Sao Paulo. In 2007 he was awarded\, jointly with U. Umirbaev\, the E. H. Moore Research Article Prize of the AMS for the solution of the Nagata problem on polynomial automorphisms. In 2009 Shestakov was elected to the Brazilian Academy of Sciences\, and in 2010 he was awarded the “Ordem de Merito Scientifico” by the president of Brazil. In 2016 Shestakov was elected a Fellow of the AMS\, and in 2017 he was awarded the Gold Medal “For Great Contributions to Mathematics” by the Sobolev Institute of Mathematics (Novosibirsk\, Russia). Shestakov’s interests lie in the Ring Theory and Combinatorial Algebra. He has focused on the structure and representations of non-associative algebras and superalgebras\, PIalgebras\, free algebras and their automorphisms. \nConnection Details \nTo attend in person: \n     Room EN-2006\, S.

SUMMARY:AARMS Geophysical Inverse Problems Discussion
DESCRIPTION:Farquharson\, 2008\, Constructing piecewise-constant models in multidimensional minimum-structure inversions.\nAlso available on the author’s webpage: https://www.esd.mun.ca/~farq/special.html \nConsidering the discussion at our previous meeting\, it seems natural to next look at methods for recovering sharp/blocky/compact features. This one is a relatively short paper\, going back to a time when most inversion work was on rectilinear meshes\, and it would be sensible to return to these ideas now that unstructured meshes are seeing more use.

SUMMARY:Combinatorial Algebra meets Algebraic Combinatorics  2023
DESCRIPTION:Combinatorial algebra and algebraic combinatorics are two highly\nactive areas of research. Their importance is felt throughout\ntheoretical and applied mathematics\, including algebraic geometry\,\nrepresentation theory\, commutative algebra\, and mathematical physics;\nthey have found numerous practical applications in diverse fields. \nThe connections between these overlapping subjects are central to\nthe CAAC workshops’ traditional thematic goals. They were\nemphasized in a series of expository lectures which were given by\nTony Geramita and Fran\c{c}ois Bergeron in January 2004 at\nQueen’s University. Through these lectures\, it became evident\nthat interesting special cases of Macaulay’s inverse systems\, a\nfundamental concept in commutative algebra\, are essentially the\ncoinvariant spaces which arise in algebraic combinatorics. These\nconnections led to collaborative interdisciplinary research among\ntwo historically disjoint communities of scholars. \nThe CAAC meeting has been held annually since 2004. It\nfocuses on the continually evolving interactions between combinatorial\nalgebra and algebraic combinatorics.

SUMMARY:Atlantic General Relativity Meeting 2022
DESCRIPTION:This series of annual meetings focusses on recent advances in all aspects of classical and quantum gravity. Topics include mathematical general relativity\, relativistic astrophysics\, gravitational waves\, cosmology\, gravitational aspects of string theory\, loop quantum gravity\, and numerical relativity. There is particular focus on the development of graduate students and postdoctoral fellows. As in previous years\, there is a two day workshop during which three invited experts (from outside the Atlantic region) give introductory lectures aimed on current topics of high interest. This is followed by two days of contributed research talks\, with prizes given to the best student and postdoctoral fellows. While originally aimed to foster collaboration between research groups in Atlantic Canada\, in recent years\, the conference has attracted participants from both the rest of Canada and abroad.

SUMMARY:CMS-UPEI-AARMS Regional Math Camp
DESCRIPTION:The School of Mathematical and Computational Science (SMCS) is once again organizing the UPEI-CMS-AARMS Regional Math Camp\, to be held at UPEI between May 6 – May 8\, 2022. We anticipate hosting some of the most talented grade 10 and grade 11 math students from across the Island. This year\, we expect to invite 25-30 students. We offer students an opportunity to participate in challenging\, intellectual activities with their peers\, guided by the UPEI SMCS faculty members. The students will arrive on the UPEI campus by 9:00 am on Friday (May 6)\, spend 2 nights in residence\, and depart at noon on Sunday (May 8). With the help of several undergraduate math majors\, faculty members will conduct several educational\, problem-solving and career sessions during the daytime\, and recreational sessions during the evenings. The students will be chaperoned at all times\nthroughout the weekend.

SUMMARY:AARMS Scientific Machine Learning Seminar: Michael W. Dunham (Department of Earth Sciences\, Memorial University)
DESCRIPTION:Semisupervised machine learning algorithms and their application to geoscience classification problems\n\nIn recent years\, many disciplines have been challenged with trying to efficiently extract meaning\, or value\, out of large datasets. Technological advances have improved data storage capabilities as well as how data can be obtained (e.g.\, real-time data). Manually interpreting data that are exponentially growing in volume has obvious management and analysis challenges. Machine learning is a solution to these challenges. Machine learning algorithms teach computers to recognize patterns in data and assign repetitive patterns to similar categories. This process automates pattern recognition of data and allows meaningful information to be extracted in an efficient manner.\n\n\nFor many machine learning problems\, there are sufficient data to train a wide range of algorithms. Some applications\, such as image classification and speech recognition\, have large training datasets readily available. However\, in several geoscience-related problems\, labeled data are generally obtained by sampling the earth in some manner (e.g.\, drilling wells\, field sampling\, etc.)\, which is not trivial due to cost and logistical factors. As such\, many earth science-related machine learning problems have limited training data. Supervised machine learning algorithms are prone to overfitting in scarce training data situations\, but semisupervised approaches are designed for these problems because the unlabelled data are also used to inform the learning process.\n\nThree geoscience applications inherently challenged with limited training data are well log classification\, seismic classification\, and bedrock lithology mapping. I apply various semisupervised algorithms to these three geoscience problems and determine if semisupervised algorithms can perform better than supervised methods and under what conditions\, if applicable. The semisupervised methods I consider are self-training\, label propagation\, and semisupervised Gaussian mixture models. I consider several supervised methods in my work\, but the most prevalent are gradient boosting decision tree methods (e.g.\, XGBoost\, LightGBM). The results show that semisupervised methods can outperform their supervised counterparts for each of the geoscience applications\, but there are situations where this is not always the case. Nonetheless\, semisupervised methods are rarely considered for many geoscience disciplines\, which is supported by the lack of published examples in the literature. The outcomes of this work help fill this gap\, but they also help raise the awareness of semisupervised methods.\n\n\nWebex link:\n\nhttps://mun.webex.com/mun/j.php?MTID=mf0e24b554219c531763a22ffce2e82c9

SUMMARY:Atlantic Graph Theory Seminar: John Engbers (Marquette University)
DESCRIPTION:Extremal questions for vertex colorings of graphs\n\nFor graphs $G$ and $H$\, an $H$-coloring of $G$ is a map from the vertices of $G$ to the vertices of $H$ so that an edge in $G$ is mapped to an edge in $H$.  The graph $H$ can be thought of as the allowable coloring scheme: its vertices are the colors used and its edges indicating colors that can appear on the endpoints of an edge in $G$. When the graph $H$ is the complete graph $K_q$\, an $H$-coloring corresponds to a proper vertex coloring of $G$ with $q$ colors; when $H$ is an edge with one looped endvertex\, an $H$-coloring corresponds to an independent set in $G$.After familiarizing ourselves with the notion of an $H$-coloring\, we will consider the following extremal graph theory question: given a family of graphs and an $H$\, which graph in the family has the most number of $H$-colorings\, and which has the least number of $H$-colorings?  We will discuss some things that are known (and not known!) in a variety of families\, including trees and graphs with a fixed minimum degree.\n\n\nJoin Zoom Meeting: link\n\n\n
