We will describe a rigorous perturbative quantization of the Btwisted topological sigmamodel via AKSZformalism on derived mapping space around constant maps. We show that the first Chernclass of the target manifold is the obstruction to the quantization, and the factorization algebra of observables on CalabiYau target give the expected topological correlation functions in the Bmodel. This is joint work with Qin Li.
