... A simple Virasoro vertex algebra is rational (and -2 semisimple as well) iff its central charge is of the form c = 1 - 6(pppp ) , where p, p are relatively prime integers, greater than 1 (which are central charges of the so called minimal models). A simple affine vertex algebra Vk (g), attached to a simple Lie algebra g is rational (and semisimple as well) iff its level k is a non-negative integer. ... We call such f an exceptional nilpotent and such k an exceptional level. ...
