Friday's Topology Seminar 2019-2020 |
Speaker: Michelle Strumila (University of Melbourne) Abstract: Infinity categories are a way of taking categories up to homotopy. This talk is about how this can be extended to infinity operads, along with generalisations to the non-directional and higher genus cases. See the calendar for upcoming events. Speaker: Eva Belmont (Northwestern University) Abstract: The Adams spectral sequence is one of the main tools for computing stable homotopy groups of spheres. In this talk, I will give an introduction to the Adams spectral sequence in motivic homotopy theory over C and over R, and describe some connections with classical and C_2-equivariant homotopy theory. I will describe joint work with Dan Isaksen to compute the motivic Adams spectral sequence over R and obtain applications to the Mahowald invariant. Speaker: Assaf Libman (Aberdeen University) |
