Vertex $F$ -algebras and their $ϕ$ -coordinated modules

Haisheng Li

In this paper, for every one-dimensional formal group $F$ we formulate and study a notion of vertex $F$ -algebra and a notion of $ϕ$ -coordinated module for a vertex $F$ -algebra wher…

Twisted modules and pseudo-endomorphisms

Haisheng Li

We exhibit a connection between two constructions of twisted modules for a general vertex operator algebra with respect to inner automorphisms. We also study pseudo-derivations, ps…
