An application of collapsing levels to the representation theory of affine vertex algebras

Drazen Adamovic, Victor G. Kac, Pierluigi Moseneder Frajria +2

We discover a large class of simple affine vertex algebras $V_k(\mathfrak{g})$, associated to basic Lie superalgebras $\mathfrak{g}$ at non-admissible collapsing levels $k$, havin…
