报告摘要:

In this talk, wewill review the correspondence between 4d N=2 superconformal field theories(SCFTs) and 2d vertex operator algebras (VOAs). For 4d SCFTs from M5 branes,corresponding VOAs are W-algebras with an explicit construction. Observables inboth Higgs and Coulomb branches of SCFTs are identified with data in VOAs.Various new interesting properties of 2d VOAs such as level-rank duality,conformal embedding, collapsing levels, coset constructions for known VOAs canalso be derived from 4d theory.
