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...

Results on a two way convection-diffusion problem; an asymptotic error analysis on a piece-wise uniform grid; and a framework for understanding quadrature errors in Finite Element Methods are presented. These results were never published, although I...

The cohomology ring of the Grassmannian, the set of k-dimensional subspaces in n-dimensional space, can be described by Schur functions, a symmetric function that are characters of the special linear Lie group. To study the K-theory ring, the...

Please bring your favourite (math) problems. Anyone with a problem to share will be given about 5 minutes to present it. We will also choose most of the speakers for the rest of the semester.

Different mathematical models (direct and indirect transmission models) were used to understand and analyze different infectious diseases dynamics and possible prevention and/or elimination strategies. As a first step, an age of infection model with...

For periodic links, we show that the Khovanov space of Lipshitz-Sarkar admits a natural cyclic group action, and identify its fixed point set. As an application, we prove that the Khovanov homology (with coefficients in the field of p elements) of a...

We consider the problem of answering queries about formulas of first-order logic based on background knowledge partially represented explicitly as other formulas, and partially represented as examples independently drawn from a fixed probability...

I will talk about applying manifold calculus to study the Lagrangian embeddings in a symplectic manifold. Using Gromov's h-principle for directed embeddings, we will prove that the analytic approximation of the Lagrangian embeddings functor is the...
