# Integral lattices in TQFT and integral modular categories

Date:
Friday 17th April 2009 - 16:20 to 17:00
Abstract:
The SO(3)-TQFT at an odd prime has a natural integral structure. It means that all matrix coefficients of the mapping class group representations in this theory are algebraic integers. I will discuss the structure of the resulting "integral modular functor". This is joint work with Patrick Gilmer.
