Meromorphic open-string vertex algebras and twisted modules from Courant algebroids
Qixuan Fang, Fei Qi
We construct a sheaf of -graded meromorphic open-string vertex algebras from a transitive Courant algebroid equipped with a generalized metric and a chos…

Boson-fermion meromorphic open-string vertex algebras and their canonically twisted modules
Qixuan Fang, Yi-Zhi Huang, Fei Qi
We construct a -graded meromorphic open-string vertex algebra from a finite-dimensional vector space with a nondegenerate symmetric bilinear form, together wi…
