"Zeta regularized determinants "

Time: 11:00

Room: MC 108

I will show how to compute the zeta regualrized determinants of differential operators, notably Jacobi operators in differential geometry and the Sturm-Liouville operators on the line. Note: this talk was cancelled last week. So this is the first part.

Homotopy Theory

"(2)-Category Theory in HoTT"

Time: 13:30

Room: MC 107

In this talk I will describe the development of category theory within HoTT and what it means for a category to be univalent.

Geometry and Combinatorics

"Equivariant cohomology of smooth toric varieties, II"

Time: 16:00

Room: MC 108

We continue by proving Brion's theorem identidying the equivariant cohomology of a smooth toric variety with the ring of piecewise polynomials on the associated fan. Then we compare piecewise polynomials to the Stanley-Reisner ring. We conclude with some remarks about non-equivariant cohomology.
