On the cohomology of meromorphic open-string vertex algebras
Fei Qi
This paper generalizes Huang's cohomology theory of grading-restricted vertex algebras to meromorphic open-string vertex algebras (MOSVAs hereafter), which are noncommutative gener…

The first cohomology, derivations and the reductivity of a (meromorphic open-string) vertex algebra
Yi-Zhi Huang, Fei Qi
We give a criterion for the complete reducibility of modules satisfying a composability condition for a meromorphic open-string vertex algebra using the first cohomology of the…

On modules for meromorphic open-string vertex algebras
Fei Qi
We study representations of the meromorphic open-string vertex algebra (MOSVAs hereafter) defined in [H3], a noncommutative generalization of vertex (operator) algebra. We start by…
