Mathematics Colloquium
The Mathematics Department Colloquium is a quarterly series of invited speakers from all mathematical fields and geared toward a broad audience. Archives can be found here.
The talks are generally every Tuesday from 4-5 PM, with an informal tea beforehand. It will be held virtually this quarter, via Zoom, on Tuesdays at 4:00pm California Time -- bring your own beverage.

In and around stable homotopy groups of spheres
The computation of stable homotopy groups of spheres is one of the most fundamental problems in topology. Despite its simple definition, it is notoriously hard to compute. It has connections to many areas of mathematics. In this talk, I will discuss a recent breakthrough on this problem, which makes use of motivic homotopy theory in a critical way. I will also talk about applications to smooth structures on spheres, and towards the open problem of Kervaire invariant one in dimension 126.
