The correspondence between four-dimensional $${\mathcal {N}}=2$$ N = 2 superconformal field theories and vertex operator algebras, when applied to theories of class $${\mathcal {S}}$$ S , leads to a rich family of VOAs that have been given the monicker chiral algebras of class$${\mathcal {S}}$$ S . A remarkably uniform construction of these vertex operator algebras has been put forward by Tomoyuki Arakawa in Arakawa (Chiral algebras of class $${\mathcal {S}}$$ S and Moore…

We study the representation theory of the $\mathcal{W}$-algebra $\mathcal{W}_k(\bar{\mathfrak{g}})$ associated with a simple Lie algebra $\bar{\mathfrak{g}}$ at level k. We show that the “-”
