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...

Neural networks are remarkable families of non-linear functions that form the backbone for state-of-the-art algorithms in tasks from computer vision (self-driving cars), natural language processing (Google Translate) and reinforcement learning...

I will discuss recent new developments in De Giorgi Conjecture for Allen-Cahn equation. In dimensions up to 10, we shall establish the C2,α estimates of level sets for stable solutions of Allen-Cahn. By applying reverse gluing method we show that the...

Lattice cohomology is a combinatorial invariant of isolated singularities of complex surfaces introduced by Ozsvath Stipsicz and Szabo, and independently by Nemethi. The construction, inspired by Heegaard Floer homology, was recently employed by...

This talk will focus on two topics in the foundations of neural networks: computability and false structures. In the first part I will recall briefly the concept of recursive functions and then discuss the gap between existence results, the...

A one-day workshop on Using R with Professor John Braun from the University of British Columbia (Okanagan), is the latest in the increasingly popular and high-quality series of workshops offered by the University of Calgary Biostatistics Centre (UCBC...
