The Erdős-Ko-Rado (EKR) theorem states that if n and k are two positive integers such that n≥2k and F is a family of k-subsets of {1,2,…,n} such that A∩B≠∅, for all A,B∈F, then |F|⩽(n−1k−1). Moreover, if n⩾2k+1, then equality holds if and only if...

We study a diffusive nutrient-phytoplankton-zooplankton-detritus (NPZ) model with delayed nutrient recycling. We consider both the case of a general spatio-temporal delay and a specific delay kernel where the model is equivalent to a non-delayed...

The Tutte polynomial of a graph is a two-variable polynomial, which is the universal polynomial satisfying deletion contraction recursion. In this talk I will explain how this polynomial arises from considering the cohomology of hypertoric varieties...

We consider stochastic and finite-sum optimization problems with deterministic constraints. Existing methods typically focus on finding an approximate stochastic solution that ensures the expected constraint violations and optimality conditions meet...

Students of grades 5 to 7 are invited to challenge and develop their thinking and creativity skills at the Math Circle Workshops. This is an enrichment program for students organized by the faculty members of the Department of Mathematics at the...

We will briefly describe our own use of AI tools in research, software, writing, supervision and administration, and raise some questions about what this will do to publishing, training and the profession.

Understanding how cells change over time is fundamental to studying development, differentiation, and regeneration. Recent advances in single-cell genomics provide detailed measurements of cellular states, but these measurements are typically limited...

Perfect codes in the Hamming metric over prime power alphabets were completely classified in the 1970s. For more general alphabets, analogous classifications were obtained for such codes correcting at least three errors. The case of 2-error...

Formal schemes were introduced by Grothendieck to geometrize the idea of taking the completion of a ring which corresponds to taking “formal” analytic / power series functions around a closed subset. They find a lot of use in deformation theory in...
