Abstract:
Commutative vertex algebras arising as subalgebras of the vertex algebras corresponding to the Kac–Moody algebras are studied. Systems of defining relations and degenerations into algebras with quadratic relations are described. The results can be used to obtain fermionic formulas for characters.
Keywords:
vertex algebras, Abelianization, quadratic algebras.
