Abstract: Previously, we introduced a notion of vertex bialgebra and a notion of module vertex algebra for a vertex bialgebra, and gave a smash product construction of nonlocal vertex algebras. Here, we introduce a notion of right comodule vertex algebra for a vertex bialgebra. Then we give a general construction of quantum vertex algebras from vertex algebras witha right comodule vertex algebra structure and a compatible (left) module vertex algebra structure for a vertex bialgebra H. As an application, we obtain a family of deformations of the lattice vertex algebras. This is based on a joint work with Naihuan Jing, Fei Kong and Shaobin Tan.
