Modelling the composition and the dynamic of the Earth subsurface is a difficult problem, which requires the implementation of efficient numerical methods for partial differential equations and of advanced statistical methods for analyzing experimental data as well as comparing them with synthetic data produced by mathematical models. In this session we will bring together mathematicians and geophysicists to present and discuss some trends in geophysical modelling and computational geophysics. Topics will include the following: -Domain decomposition methods (optimized Schwarz methods)…

Decomposition of graphs, particularly decomposition into cycles, is a vibrant area of research in the intersection of graph theory and the theory of combinatorial designs. For almost two centuries, professional as well as amateur mathematicians have been intrigued by problems that are easy to state yet extremely difficult to solve. In the last couple of decades, we have witnessed an explosion of new results, including new techniques and solutions to many long-outstanding problems; however, many fundamental problems remain unsolved. The…

Designs and codes are very active areas of research in combinatorics. There have been numerous breakthroughs in recent years, such as the existence proof for Steiner systems for arbitrary values of t. Research in designs, codes and their interaction includes both mathematical and algorithmic questions. Proofs encompass both constructions and probabilistic methods, and employ diverse mathematical techniques from algebra, number theory, graph theory, etc. In addition, there are numerous applications, in areas such as cryptography, in which designs and codes…

The Queer and Trans Mathematicians in Combinatorics conference (QTMC) is a first-ever event in combinatorics specifically aimed at queer and trans mathematicians. It aims to bring together and support queer and trans combinatorists. The conference promotes a supportive and active collaborative environment for the participants and aims to bring about visibility to an otherwise underrepresented invisible minority in the combinatorics community. The QTMCis heavily geared toward students, postdocs and early career mathematicians who are queer and/or trans.

The conference “Quantum Gravity 2020“ has a deliberately broad scope. We aim to include participants from all current approaches to quantum gravity, as well as researchers working on the phenomenology of quantum gravity. The main goal of the meeting is to assess the progress made and to constructively and openly discuss open questions in our understanding of quantum gravity. A second goal is to work towards combining the insights gained in the various approaches. In its overall goal as well…

We propose a multi-year, multi-level approach to promoting diversity and inclusivity in STEM. The annual two-week program encompasses concurrent, partially overlapping events targeting two distinct groups: (a) A summer school for top undergraduate women in Canada and the northwest United States, specializing in mathematics or a related STEM field such as computer science, physics and statistics. The program will expose them to the many facets of the mathematical sciences in an intense two week immersion. Career opportunities in academia and…
