Lattice Yang-Mills theories are important models in particle physics. They are defined on the d-dimensional lattice ℤd using a group of matrices of dimension N, and Wilson loop expectations are the fundamental observables of these theories. Recently...

The evolution and maintenance of cooperation is a fundamental problem in evolutionary biology. Because cooperative behaviors impose a cost, Cooperators are vulnerable to exploitation by Defectors that do not pay the cost to cooperate but still...

Double dimers are superimposition of two perfect matchings. Such superimpositions can be decomposed into disjoint simple loops. The question we address is: as the graphs become large, in a 'typical' double dimer sample, do some of the loops diverge...

In this talk, we will discuss a well-known formula of Ramanujan and its relationship with the partial sums of the Möbius function. Under some conjectures, we analyze a finer structure of the involved terms. It is a joint work with Steven M. Gonek...

In recent years, classical knowledge-driven approaches for inverse problems have been complemented by data-driven methods exploiting the power of machine and especially deep learning. Purely data-driven methods, however, come with the drawback of...

Fluid-structure interaction (FSI) is ubiquitous in nature and occurs at molecular to environmental scales, from the writhing of DNA in nucleoplasm, to the beating of cilia and flagella and the projection of lamellipodia and bleb-like protrusions by...

Physics-Informed Neural Networks (PINNs) have received much attention recently due to their potential for high-performance computations for complex physical systems, including data-based computing, systems with unknown parameters, and others. However...

In this talk we’ll continue to get to know bicategories by learning about what you can do inside a bicategory. We’ll learn about pasting diagrams as well as adjoints and equivalences inside bicategories before presenting some examples of what these...

The autumn 2024 edition of the West Coast Optimization Meeting will be held on 20–21 September, 2024 on the Vancouver Campus of the University of British Columbia. The organizers (Michael Friedlander, Mark Schmidt, and Philip Loewen) are pleased to...

In 1770 Euler observed that $3^3+4^3+5^3=6^3$ and asked if there was another perfect power that equals the sum of consecutive cubes. This captivated the attention of many important mathematicians, such as Cunningham, Catalan, Genocchi and Lucas. In...
