Gerstenhaber bracket on double Hochschild complex and deformation theory
Boris Shoikhet
We construct a differential and a Lie bracket on the space\linebreak $\{\Hom (A^{\otimes k}, A^{\otimes l})\},_{k,l\ge 0}$ for any associative algebra . The restriction of this…

On the Kontsevich and the Campbell-Baker-Hausdorff deformation quantizations of a linear Poisson structure
Boris Shoikhet
For the Kirillov-Poisson structure on the vector space $\g^*$, where $\g$ is a finite-dimensional Lie algebra, it is known at least two canonical deformations quantization of this…
