The correspondence between four-dimensional $${\mathcal {N}}=2$$
N
=

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 $${\mathcal {S}}$$
