"Combinatorial Algebra meets Algebraic Combinatorics" (CAAC) is a series of annual workshops that has been meeting since 2004. The main achievement of these meetings is the establishment of an ongoing dialogue between two separate research groups who...

We study the κ-color cyclic particle system on the one-dimensional integer lattice, first introduced by Bramson and Griffeath. In their original article they show that almost surely, every site changes its color infinitely often if κ ∈ {3, 4} and...

Epithelial cells organize themselves into tubes for the necessary functions of gas and nutrient transport, and the production and secretion of hormones and enzymes. Such tubes result from the organization and collective motion of a flat sheet of...

In Euclidean space, a periodic configuration is a union of finitely many translations of a lattice. In particular, energy-minimizing periodic configurations are those which possess minimum energy. Finding energy-minimizing periodic configurations is...

In this first talk out of two, I will review various well-known algorithms for integer multiplication, such as schoolbook multiplication, Karatsuba multiplication, FFT multiplication, and the Schoenhage-Strassen algorithm. The talk will also be an...

We study Caccioppoli’'s inequalities of the non-stationary Stokes equations and Navier-Stokes equations. Our analysis is local near boundary and we prove that, in contrast to the interior case, the Caccioppoli’'s inequalities of the Stokes equations...

A natural way to understand groups visually is by examining objects on which the group has a natural permutation action. In fact, this is often the way we first show groups to undergraduate students: introducing the cyclic and dihedral groups as the...

Due to incliment weather at UBC- Vancouver, this seminar is cancelled and will be rescheduled later. The notion of conformal walk dimension serves as a bridge between elliptic and parabolic Harnack inequalities. The importance of this notion is due...

Due to inclement weather, this talk has been cancelled and will be rescheduled for a later date. Bacteria collective migration can spontaneously emerge when individuals follow common rules of interaction (chemotaxis), and a biased leakage during the...

This talk is devoted to variational problems on the set of probability measures which involve optimal transport between unequal dimensional spaces. In particular, we study the minimization of a functional consisting of the sum of a term reflecting...
