General twisting of ϕ1-coordinated modules of nonlocal vertex algebras

Abstract

We introduce a notion of [Formula: see text]-coordinated module twistor for a [Formula: see text]-coordinated module of a nonlocal vertex algebra. Furthermore, we study twisted tensor products and L-R-twisted tensor products of [Formula: see text]-coordinated modules of nonlocal vertex algebras and we unify these two constructions by [Formula: see text]-coordinated module twistors.
