2nd workshop of AARMS CRG on Mathematical Foundations of Scientific Machine Learning
This is the 2nd workshop of the AARMS Collaborative Research Group on Mathematical Foundations in Scientific Machine Learning, which will be held on the Fredericton Campus of the University of New Brunswick on Jul 31 - Aug 01, 2023. The theme of the workshop is as broad as the scientific research programs of the partners in the AARMS CRG group, including Machine Learning approaches in Mathematics, Geophysics, Chemistry, Statistics, etc.

Atlantic Graph Theory Seminar
Time: 3.30pm, Atlantic time, Wednesday Sept.20 Speaker: Jessica McDonald, Auburn University Title: On flows (and group-connectivity) in signed graphs Abstract: In this talk we'll start by discussing flows in signed graphs and how it generalizes the usual notion of integer flows in graphs. In particular, flow-colouring duality of graphs in the plane can be re-interpreted using signed graphs in the projective plane. Also, where a flow in a graph can be viewed as a sum of flows on cycles, in…

Atlantic Graph Theory Seminar
Speaker: Iain Beaton, Acadia University Title: On the Unimodality of Nearly-Well Dominated Trees Abstract: A polynomial is said to be unimodal if its coefficients are non-decreasing and then non-increasing. The domination polynomial of a graph G is the generating function of the number of dominating sets of each cardinality in G, and its coefficients have been conjectured to be unimodal. In this talk we will show the domination polynomial of a tree T is unimodal so long as the sizes of the minimal…

The Science Atlantic Mathematics, Statistics, and Computer Science Conference is an annual regional event. It provides a platform for undergraduate students in Mathematics, Statistics and Computer Science at Atlantic Canadian universities to disseminate their research projects, participate in contests, and network with other students in the region. It also serves as a networking event for faculty members of Atlantic Canadian universities. In 2023, University of Prince Edward Island will host the conference in Charlottetown, PEI. The dates of the conference…

The purpose of this event is to establish and enhance research networks among women and female identifying mathematicians who work in the areas of mathematics related to commutative algebra. It will be the second of its kind. The first one (Banff 2019) was an amazing success, with many of the groups still working together. It has led to a strong network that besides research, provides visibility for women and many opportunities for professional development. It has also served as an…

Two short talks by grad students Alex Clow and William Kellough. 'Live' viewing in Chase 227 for those at Dalhousie. Talk 1: Alex Clow, Simon Fraser University Polynomially Bounding the Oriented Chromatic Number in Euler Genus In this talk we consider the oriented chromatic number of graphs with bounded Euler genus. In particular, we present our proofs that the oriented chromatic number is at most $g^{6400}$ for sufficiently large $g$ and at least $\Omega((\frac{g^2}{\log g})^{1/3})$. This is a major improvement…

Atlantic Graph Theory Seminar
Detecting (Di)Graphical Regular Representations Speaker: Joy Morris, U. Lethbridge Abstract: Graphical and Digraphical Regular Representations (GRRs and DRRs) are a concrete way to visualise the regular action of a group, using (di)graphs. More precisely, a GRR or DRR on the group $G$ is a (di)graph whose automorphism group is isomorphic to the regular action of $G$ on itself by right-multiplication. For a (di)graph to be a DRR or GRR on $G$, it must be a Cayley (di)graph on $G$. Whenever…

Speaker: Santiago Guzman-Pro, TU Dresden Title: Forbidden Tournaments and the Orientation (Completion) Problem Abstract: For a fixed finite set of oriented graphs F, the F-free orientation problem asks whether a given finite undirected graph G has an F-free orientation, i.e., whether the edges of G can be oriented so that the resulting oriented graph does not contain any oriented graph from F as an oriented (induced) subgraph. It was first noted by Bang-Jensen, Huang, and Prisner that when F…

The UNB Data Challenge 2023 will bring together two competitive tracks, Data Visualization (8th Annual), and Data Analytics (4th Annual) on Nov. 24, 2023, in a virtual format! Take up the challenge and demonstrate the power of data. Participants and teams will have the chance to showcase their ability to tell a story driven by data in unique competitive formats. Teams can participate in both tracks. It is an ideal setting for citizens to get engaged, meet leaders in academia,…
