The Banff International Research Station will host the "Alberta Number Theory Days XII (ANTD XII)" workshop from May 2, 2020 to May 3, 2020. Number theory is a broad and central area of research with many connections and applications to other areas...

In this talk we introduce Microlinear Lawvere theories, and show that differential objects in cartesian tangent categories are an example. One of the more striking applications of this theory is that every tangent category embeds into the Eilenberg...

I will introduce deformations of lattice cohomology corresponding to the knot homologies found by Ozsváth, Stipsicz and Szabó in https://arxiv.org/abs/1407.1795. If time permits I will show that by means of holomorphic triangles counting, one can...

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...
