On the Hochschild cohomologies of associative conformal algebras with a finite faithful representation

30 Oct 2018  ·  Kolesnikov P. S., Kozlov R. A. ·

Associative conformal algebras of conformal endomorphisms are of essential importance for the study of finite representations of conformal Lie algebras (Lie vertex algebras). We describe all semisimple algebras of conformal endomorphisms which have the trivial second Hochschild cohomology group with coefficients in every conformal bimodule... As a consequence, we state a complete solution of the radical splitting problem in the class of associative conformal algebras with a finite faithful representation. read more
