Title: Universal objects in vertex algebra theory

Abstract: This is a sequel to my first talk on trialities of Walgebras. I will discuss the notion of universal objects, which are certain vertex algebras defined over commutative rings. They are useful for classifying vertex algebras with prescribed strong generating types. The twoparameter vertex algebra W(c,\lambda) which appears in the proof of the GaiottoRapcak triality conjecture, is an example of such a universal object. I will give some further details about this construction and how it is used to prove the triality conjecture.
