https://www.youtube.com/watch?v=8nm2ByS5NnY 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.
