On a Lie Algebraic Approach to Abelian Extensions of Associative Algebras
Published online by Cambridge University Press: 26 March 2020
Abstract
By using a representation of a Lie algebra on the second Hochschild cohomology group, we construct an obstruction class to extensibility of derivations and a short exact sequence of Wells type for an abelian extension of an associative algebra.
