An oriented graph is a digraph with at most one arc between any pair of vertices. We say that the action of a group on a set of points is regular if it is sharply transitive; that is, there is exactly one group element mapping any point to any other...

Microtubules and motor proteins interact in vivo and in vitro to form higher-order structures such as bundles, asters, and vortices. In vivo, the organization of microtubules is connected directly to cellular processes such as cell division, motility...

This talk addresses how the calculus-of-variations is applied to non-linear elasticity. In physically realistic classical models, energy-minimizing deformations may not be smooth enough to satisfy the variational Euler-Lagrange equations. However...

We present mod-two cohomology of both symmetric and alternating groups as (almost) Hopf rings. As is being seen in subjects such as representation stability, in these settings one gains substantial insight by considering all cases together, binding...

BC Safety Authority’s accident prevention strategy follows a risk based platform, called “bow tie” for ongoing management and prevention of major incidents. The bow tie method draws on the direct experience of safety management team and the data...

Statistics of measurement outcomes in quantum mechanics is described by a map that associates a matrix to each possible measurement outcome. The probability of this outcome is then given by a trace of this matrix. Probability of a sequence of...

Topology is full of ineffective arguments constructing objects and equivalences by algebra. One of the great early achievements of algebraic topology was the work of Thom, followed by Milnor and Wall, on cobordism theory, which describes when a...

Binding of molecules, ions or proteins to small target sites is a generic step of cell activation. This process relies on rare stochastic events where a particle located in a large bulk has to find small and often hidden targets. I will present in...

Let f be a primitive modular form and L(s) its associated L-function. Anton Good (1982) bounded |L(s)| by approximately the cube root of the distance from the real axis on the line s = 1/2, in the case f is a modular form on the full modular group...
