摘要:
这是此前由我们之一发起的关于非局部顶点双代数与碎积非局部顶点代数研究的延续。本文中,我们针对非局部顶点双代数 H 研究右 H-余模非局部顶点代数的概念,并给出顶点代数形变的一种构造,该形变同时具有右 H-余模非局部顶点代数结构和相容的 H-模非局部顶点代数结构。我们还给出碎积非局部顶点代数的 ϕ-协调拟模构造。作为例子,我们通过形变与非退化偶格相关联的顶点代数,给出一族量子顶点代数。
英文摘要:
This is a continuation of a previous study initiated by one of us on nonlocal vertex bialgebras and smash product nonlocal vertex algebras. In this paper, we study a notion of right $H$-comodule nonlocal vertex algebra for a nonlocal vertex bialgebra $H$ and give a construction of deformations of vertex algebras with a right $H$-comodule nonlocal vertex algebra structure and a compatible $H$-module nonlocal vertex algebra structure. We also give a construction of $ϕ$-coordinated quasi modules for smash product nonlocal vertex algebras. As an example, we give a family of quantum vertex algebras by deforming the vertex algebras associated to non-degenerate even lattices.
