There are simple formulas defining "naive entropy" for continuous/measure preserving actions of a countable group G on a compact metric/probability space. It turns out that if G is amenable, then this naive entropy coincides with topological...

The symmetric algebra is known for being the free commutative algebra over a vector space. Therefore, it is universal amongst commutative algebras. It turns out, the symmetric algebra also has another universal property which can be used to construct...

Plumbed three-manifolds are those three-manifolds that can be be realized as links of isolated complex surface singularities. Inspired by Heegaard Floer theory Nemethi introduced a combinatorial invariant of complex surface singularities (lattice...

The horospherical flow on finite-volume hyperbolic surfaces is well-understood. In particular, effective equidistribution of non-closed horospherical orbits is known. New difficulties arise when studying the infinite-volume setting. We will discuss...

In this talk, we will use compartmental models to examine the power of age-targeted mitigation strategies for COVID-19. We will present evidence that, in the context of strategies which end with herd immunity, age-heterogeneous strategies are better...

Case of the Gauss map

I will discuss how cartesian restriction categories can be reasoned about using string diagrams for monoidal categories, including how this extends to regular restriction categories. Specifically, we will see that every cartesian bicategory of...

I will present some of the mathematics we have been using at the Institute for Health Metrics and Evaluation (IHME) in the UW School of Medicine to project the global course of the COVID outbreak and the demands it may put on local health systems...
