Expanders and torsion homology
Science Center 530We say that a Riemannian 3-manifold has good higher expansion if every rationally null-homologous i-cycle bounds a relatively small i+1 chain. In this talk, I'll explain how to construct rational […]
Macdonald-Hurwitz numbers and alternating path operators
Science Center 232Hurwitz numbers count inequivalent branched coverings of the sphere by an orientable surface with a given number of ramification points. Some specializations of the generating function of Hurwitz numbers are […]
Universal Constructions: Drinking the Kool-Aid of the Universe
Mathematics is full of seemingly unrelated structures which can be unified via universal constructions. In this talk, we’ll dive into the concept of universality, revealing how universal properties—often seen as […]
