Motivated by cotyledon patterns in conifer embryos, we study pattern emergence in solutions of systems reaction-diffusion partial differential equations on evolving curved surfaces. We start by reviewing results on a static domain. Then, we go over...

We shall give an overview of what Khovanov cohomology and its relatives have told us about knot concordance over the past 15 years. No knowledge required. Includes joint work with Lukas Lewark and Peter Feller.

Epstein-Barr virus (EBV) is a ubiquitous infection worldwide and is associated with the development of several kinds of cancers. Rates of EBV replication and disease are higher in individuals who are co-infected with HIV-1; however, the causes of...

The conjugate gradient algorithm (CG) is a widely used iterative method for solving large symmetric positive definite linear systems Ax=b. Beginning in the 1980's (and, even earlier, in the thesis of Paige dating back to 1971), a great deal of...

The Math Catcher Outreach program aims to promote mathematics and scholarship in general by encouraging elementary and high school students to recognize how math is used in everyday life and how it forms the basis for many of our daily decisions and...

L-functions associated with automorphic forms are vast generalizations of Riemann zeta functions and Dirichlet L-functions. Although the theory of L-functions play a fundamental role in number theory, it is still largely conjectural. If π is an...

Let A be a finite-dimensional algebra. A fundamental theorem of Drozd shows that the complexity of the representation theory of A belongs to exactly one of three rather distinct classes, called finite, tame or wild representation type. I will explain...

It is well-known that a closed convex set C containing the origin in its interior can be represented as the 1-sublevel set of its gauge function. If the set C is compact, then the gauge is the unique sublinear function whose 1-sublevel coincides with...

We investigate the scaling limit of the range (the set of visited vertices) for a general class of critical lattice models, starting from a single initial particle at the origin. Conditions are given on the random sets and an associated ``ancestral...

The talk will be devoted to a simple introduction to stochastic PDEs (SPDEs) driven by Wiener processes, including both forward and backward (in time) cases. Some motivations, as well as the duality relationship between forward and backward SPDEs...
