Abstract

This lecture explores Hochschild cohomology as a Gerstenhaber algebra in detail, the notions of smoothness and duality, algebraic deformation theory, infinity structures,  and connections to the Hochschild-Kostant-Rosenberg decomposition. Useful homological algebra background is provided as well.
