This paper studies the ring structure of the Hochschild cohomology ring of an algebra. The first main result gives a ring homomorphism from the Hochschild cohomology ring of an algebra A to the Ext-algebra of an A-module.Then, for a one point extension B of a finite dimensional algebra A, we relate the ring structures of the …

Web1 day ago · He proved one direction of the weak conjecture, namely, that a semisimple Lie algebra has vanishing adjoint cohomology and satisfies H 1 (g, C) = 0. The outline of this paper is as follows. In the second section we recall the definition and basic properties of sympathetic Lie algebras and provide results on the adjoint cohomology of Lie algebras. WebApr 26, 2024 · How to write it down on the level of the Hochschild cohomology (not only for commutative algebras)? (Actually, it'd interesting even for symplectic manifold for which we can identify polyvector fields and differential forms and then the question will be about the de-Rham differential on the level of Hochschild cohomology).

WebThe cohomology groups of the dual complex H (A) := (Hom(A n+1 ; C ); b ) are called the Hochschild cohomology groups of A and denoted HHn (A). Since is a trace if, and only if, Æ b = 0, we obtain that HH0 (A) is indeed the space of traces on A. Clearly the groups HHn (A) are covariant functors in A, in the sense that any algebra morphism : A ! ...
