In this talk, we study the performance of some preconditioners for accelerating the convergence of Krylov subspace methods for solving linear systems of equations with a block three-by-three structure. A brief discussion is included regarding how...

We study the behavior of h-vectors associated to matroid complexes under weak maps, or inclusions of matroid polytopes. Specifically, we show that the h-vector of the order complex of the lattice of flats of a matroid is component-wise non-increasing...

In this talk I will describe some properties of Meinhardt's model of sidebranching. This is a four-species reaction-diffusion model dating from 1976 describing the interaction of four fields, the concentrations of an activator, an inhibitor, the...

The theory of combinatorial limits, which provides analytic tools to represent and study large discrete structures, resulted in new views on a wide range of topics in mathematics and computer science and also opened new connections between...

Overloading, which allows functions to exhibit different behaviors based on the types involved, is one of the most useful facilities of a typed programming language. In the Haskell programming language, this facility is provided by type classes. Type...

Please note: A separate AMD 2024 website is also available. Please see that site for up to date information about this event. The annual Alberta Mathematics Dialogue (AMD) is the largest annual meeting for professional mathematicians and mathematics...

The distance matrix of a graph records the length of the shortest path between any two vertices. Graham and Pollak found that when the underlying graph is a tree, the determinant of the distance matrix satisfies a nice, simple formula. In particular...

The inhomogeneous multispecies PushTASEP is an interacting particle system with multiple species of particles on a finite ring where the hopping rates are site-dependent. (The homogeneous variant on Z is also known as the Hammersley–Aldous–Diaconis...

What is the SRP? The UBC Mathematics Summer Reading Program (SRP) is a four to six-week program intended for first-year and second-year undergraduates. Students will work in small groups with a graduate student or postdoctoral mentor on a reading...
