Title: Weak n-categories as sheaves

Abstract:

In this talk I will outline an adjunction between weak n-categories, in the sense of Rezk, and sheaves on a site whose objects are iterated submersions of framed manifolds M^n \to M^{n-1} \to ... \to M^0. The left adjoint of this adjunction can be regarded as a categorical version of chiral homology. Along the way is established a combinatorial version of Poincare' duality. This work is joint with Nick Rozenblyum.
