L-R-Twisted Tensor Products of Nonlocal Vertex Algebras and Their Modules

Abstract

In this article, we introduce and study a common generalization of the twisted tensor product construction of nonlocal vertex algebras and their modules. We investigate some properties of this new construction; for instance, we give the relations between L-R-twisted tensor product nonlocal vertex algebras and twisted tensor product vertex algebras. Furthermore, we find the conditions for constructing an iterated L-R-twisted tensor product nonlocal vertex algebra and its module.
