In classical homotopy theory, graphs are treated as 1-dimensional CW complexes. But since the classical notions of continuous maps and their homotopies do not respect the discrete nature of graphs, this fails to capture the full combinatorial...

We consider an online strategic classification problem where each arriving agent can manipulate their true feature vector to obtain a positive predicted label while incurring a cost that depends on the amount of manipulation. The learner seeks to...

A big conjecture which emerged from the math-physics interface is that the Gromov-Witten potentials of a Calabi-Yau threefold are generalized quasi-modular objects. In on-going work, joint with Aaron Pixton, we study the case of Picard rank 3 Abelian...

I will discuss various joint works with Luca Nenna and PhD student Joshua Hiew. We show that entropically regularized optimal transport with discrete marginals and general cost functions can be characterized by a well-posed ordinary differential...

Reactive oxygen species (ROS) often get a bad reputation. They are linked to cancer formation and contribute to aging—not just of the skin but throughout the body. Given these harmful effects, it might come as a surprise that living organisms...

Let $\rm{ord}_p(a)$ be the order of $a$ in $( \mathbb{Z} / p \mathbb{Z} )^*$. In 1927, Artin conjectured that the set of primes $p$ for which an integer $a\neq -1,\square$ is a primitive root (i.e. $\rm{ord}_p(a)=p-1$) has a positive asymptotic...

This seminar will focus on aspects of the ecology of animal home ranges in which empirically derived movement tracks are viewed as realizations of continuous time, continuous space stochastic processes. Topics will include the distinctions between...

Any construction of a quantum computer requires finding a good set of universal quantum logic gates: abstractly, a finite set of matrices in U(2^n) such that short products of them can efficiently approximate arbitrary unitary transformations. The 2...

Combinatorial Configurations lay between block designs and hypergraphs. When these incidence structures can be embedded in the plane, we call them Geometric Configurations. In this talk, we will explore several results in the study of configurations...

Join us for an engaging presentation on "Unraveling the Mathematics of Single-Cell Dynamics" with Dr. Anotida Madzvamuse. This event is part of the UBC Applied Science Black Excellence in STEM (BEST) Speaker Series, in collaboration with the...
