Simon D. Lentner

There is a very general picture emerging that conjecturally describes what happens to the representation theory of a vertex algebra $V$ if we pass to the kernel $\mathcal…

Coupling a vertex algebra to a large center

Boris L. Feigin, Simon D. Lentner

Suppose a Lie group $G$ acts on a vertex algebra $V$ . In this article we construct a vertex algebra $V ~$ , which is an extension of $V$ by a big central vertex subalgebra ide…
