Cohomology and Deformation of Leibniz Pairs
M. Flato, M. Gerstenhaber, A. A. Voronov
Abstract
Cohomology and deformation theories are developed for Poisson algebras starting with the more general concept of a Leibniz pair, namely of an associative algebra A together with a Lie algebra L mapped into the derivations of A. A bicomplex (with both Hochschild and Chevalley-Eilenberg cohomologies) is essential.
