The multigraded Nijenhuis-Richardson Algebra, its universal property and application

Quantum Algebra 2009-09-25 v1

Abstract

We define two (n+1)(n+1) graded Lie brackets on spaces of multilinear mappings. The first one is able to recognize nn-graded associative algebras and their modules and gives immediately the correct differential for Hochschild cohomology. The second one recognizes nn-graded Lie algebra structures and their modules and gives rise to the notion of Chevalley cohomology.
