Conformal nets and vertex operator algebras (VOAs) are both mathematical axiomatizations of 2d chiral conformal field theories. The conformal net approach is functional analytic, and has many important applications in operator algebras, subfactors, and low-dimensional topology. The VOA approach is purely algebraic, which is closely related to the theories of (infinite-dimensional) lie algebras, modular forms, and finite groups (e.g. monster groups). Despite the methodological differences, there are many similar and parallel results in the representation theories of these two mathematical objects. So one would like to have a unifying picture, in which these two approaches are conceptually related. In this talk, I will give a brief overview of the program of understanding the relations between conformal nets and VOAs which was initiated in recent years.海报
