A method for describing the maximal ideal in universal affine vertex algebras at non-admissible levels

Drazen Adamovic, Ozren Perse, Ivana Vukorepa

The problem of determining maximal ideals in universal affine vertex algebras is difficult for levels beyond admissible, since there are no simple character formulas which can be a…
