[Binghamton Geometry Topology Seminar] Geometry and Topology seminar: Maxine Calle

[Cary Malkiewich]

Hi everyone,

A quick reminder that we are having lunch with Maxine Calle (University of
Pennsylvania) today at 12pm, meet just outside WH100E, and that she is
giving a talk today at 2:50pm. See you there!

Best,
Cary

*Title: *Nested cobordisms and TQFTs
*Abstract: *The folk theorem identifying 2-dimensional TFQTs with Frobenius
algebras is a starting point for a lot of interesting mathematics, from
mathematical physics to homotopy theory to higher category theory. In this
talk, we will explore what happens if we replace the cobordism category
with a category of nested cobordisms, where 2-dimensional surfaces may have
embedded 1-dimensional submanifolds, and what kind of algebraic structure
the corresponding nested TQFTs pick out. This is based on ongoing work
joint with R. Hoekzema, L. Murray, N. Pacheco-Tallaj, C. Rovi, and S.
Sridhar.
