Let two four-dimensional ${\cal N}=2$ SCFTs be related by an RG flow, and denote their VOA stress-tensor nilpotency indices by $\mathfrak{n}_{\rm UV}$ and $\mathfrak{n}_{\rm IR}$,…

Let $\mathfrak{rank}$ be the complex dimension of the Coulomb branch of a four-dimensional ${\cal N}=2$ SCFT. Let $\mathfrak{n}$ be the smallest positive integer such that the VOA…

Lisse-VOA conjecture. The vertex operator algebra corresponding to a 4d $\mathcal{N}=2$ SCFT is always lisse.

SCFT/chiral-algebra correspondence. The appropriate chiral algebra for ${\mathcal M}_H$ is the chiral algebra supplied by the SCFT/chiral algebra correspondence.
