On Kontsevich’s Hochschild cohomology conjecture

By P. Hu, I. Kriz and A. A. Voronov


A conjecture of Deligne stated that the Hochschild cohomology complex of an associative algebra has a natural structure of a 2-algebra, i.e. an algebra over the chain complex version of the 2-cube operad. This indicated a remarkable connection between the deformation theory of associative algebras, and the geometry o
