Abstract:

We will discuss some foundational aspects of geometry and deformation theory in the less commutative, or E_n, setting. In particular, we establish a relation between the E_n-tangent complex and E_n-Hochschild cohomology, proving a version of a conjecture of Kontsevich. Finally, we will sketch how a fuller development of E_n-geometry offers an algebro-geometric counterpart to categorical structures of topological field theory.
