Higher categories of cobordisms

CMSA EVENTS: CMSA Geometry and Quantum Theory Seminar

When: September 9, 2025
4:15 pm - 6:30 pm
Where: Science Center 507
Address: 1 Oxford Street, Cambridge, MA 02138, United States
Speaker: Lorenzo Riva (Harvard CMSA)

I will give a brief introduction to topological field theories from a higher categorical perspective. After saying a few things about higher categories, I will define a family of n-categories of bordisms and talk about their universal properties. I will try to squeeze in the canonical example — representations of the 2-dimensional oriented bordism 2-category are separable symmetric Frobenius algebras — and, time permitting, talk about my current work.
