David Ayala: Higher categories are sheaves on manifolds
University of Notre Dame2012/07/26 に公開
David Ayala, Harvard University)
Abstract: Chiral/factorization homology gives a procedure for constructing a topological field theory from the data of an E_n algebra. I'll explain a mulit-object version of this construction which produces a topological field theory from the data of an n-category with adjoints.
This construction is a consequence of a more primitive result which asserts an
equivalence between n-categories with adjoints and ``transversality sheaves'' on framed n manifolds - of which there is an abundance of examples.
This work is joint with Nick Rozenblyum.

Does a left derived functor sometimes involve "additive, contravariant, right exact" with a injective resolution?????
