Finitely generated groups can be treated as geometric objects by considering their Cayley graphs with respect to finite generating sets. All such graphs are quasi-isometrically equivalent. In the 80s, Gromov proposed studying finitely generated...

Infectious diseases such as tuberculosis, African swine fever virus (ASFV), and highly pathogenic influenza viruses continue to affect millions of people and animals worldwide. Developing vaccines or antiviral drugs against these pathogens...

To compute the quantum dynamics of a molecule's electrons, one tractable way to proceed is via time-dependent density functional theory (TDDFT). TDDFT gives equations of motion that, in principle, yield the same electron density as the full but...

Abstract TBA

A brief introduction to information theory

In arithmetic geometry, local-to-global principles capture the ways in which one approaches difficult "global" questions over number fields by studying their "local" analogues over $p$-adic fields. These principles often fail for questions about the...

A Latin square of order $n$ is an $n\times n$ grid of $n$ symbols each appearing exactly once in every row and column. If we decompose Latin squares by symbol, we can express them as sums of permutation matrices equalling a constant matrix. In this...

Despite only comprising about a quarter of the total population of Canada, foreign-born individuals bear about three-quarters of the burden of active tuberculosis (TB) cases. To investigate the impact of immigration on the burden of TB among foreign...

Weighting methods are essential tools for estimating causal effects in observational studies, with the goal of balancing pre-treatment covariates across treatment groups. Traditional approaches pursue this objective indirectly, for example, via...
