AARMS Geophysical Inverse Problems Discussion
Farquharson & Oldenburg, 2004, A comparison of automatic techniques for estimating the regularization parameter in non-linear inverse problems. Also available here: https://gif.eos.ubc.ca/sites/default/files/Farquharson_regparam_04.pdf This paper compares some common approaches for choosing the value of the regularization parameter in underdetermined, minimum-structure-type inverse problems. It can provide an overview for us before looking at more recent ideas. Friday, June 24, 2022 @ 1:30 pm – 2:30 pm (Atlantic time)

Junior Math and Computer Science Camp
This week-long day camp is an opportunity for students entering grades 5 or 6 in the Annapolis Valley to participate in fun and enriching science-based activities with Acadia faculty and students to develop their curiosity and enjoyment of math and computer science. It represents an important piece of a multi-year plan to develop the science skills of young students in the Annapolis Valley by bringing young students into the Acadia University outreach program. This will begin the process of positively…

The Canadian Undergraduate Mathematics Conference (CUMC) is a national conference organized each summer by undergraduate students for undergraduate students at different institutions across Canada. The 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…

Friday, July 15, 2022 @ 1:30 pm – 2:30 pm (Atlantic time) Bijani et al., 2017, Physical-property-, lithology- and surface-geometry-based joint inversion using Pareto Multi-Objective Global Optimization. If 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). This 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…

Lelièvre et al., 2012, Joint inversion of seismic traveltimes and gravity data on unstructured grids with application to mineral exploration. https://library.seg.org/doi/10.1190/geo2011-0154.1 If 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). This 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…

Symmetry, Invariants, and their Applications: A Celebration of Peter Olver’s 70th Birthday
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.…

The objective of the conference is to bring together an international group of experts in three areas: microlocal analysis, inverse problems and harmonic analysis. There will be 19 internationally recognized researchers in those subjects, each invited to give a lecture. There has recently been great progress in all these areas, with mutual benefits, and no end in sight. With this conference we hope to foster interaction and collaboration among speakers and other participants from the three different areas. Furthermore, the…

The Canadian Conference on Computational Geometry (CCCG) is a forum to disseminate and discuss theoretical and applied results in discrete and computational geometry. Computational geometry is concerned with the design of efficient algorithms, the development of software, and the study of the mathematical foundations of computational problems whose formulation involves geometric constraints. The field is motivated by problems from a broad range of application areas, as diverse as computer graphics and animation, computer vision, computer-aided design and manufacturing, geographic information…
