Twisted Argyres--Douglas theories: vertex algebras, Higgs branches, and double covers
Christopher Beem, Harshal Kulkarni
We investigate the associated vertex operator algebras and Higgs branches of two closely related families of generalised Argyres--Douglas theories, arising from the twisted $A_{2N}…

Towards a classification of graded unitary algebras
Christopher Beem, Harshal Kulkarni
We study constraints imposed by four-dimensional unitarity (formalised as graded unitarity in recent work by the first author) on possible vertex algebras arising…
