16:00 - 17:00 Two dimensional topological quantum field theories
Byeongho Lee (National Institute for Mathematical Sciences),
We explain what the following sentences mean: Definition: A 2-d TQFT is a symmetric monoidal functor from the category of 2-d cobordisms to that of finite dimensional vector spaces. Theorem: The category of 2-d TQFT is equivalent to that of Frobenius algebras. We also discuss briefly about the problem of orbifolding Frobenius manifolds.
