Abstract:
In joint work with Kevin Costello, we try to capture the rich structure
carried by the observables of a quantum field theory (e.g., correlation
functions) using the notion of a factorization algebra. The talk will aim
to motivate and unpack the definition before moving on to our main
theorem, which is a kind of deformation quantization for field theory. The
theorem states that the observables of a classical field theory form a
commutative factorization algebra and that the Batalin-Vilkovisky
procedure deforms this classical factorization algebra into the
factorization algebra of observables for the associated quantum field
theory. Time permitting, we may discuss examples or the relationship to
TFTs (Lurie's topological chiral homology and Morrison-Walker's blob
homology).
