顶点代数的扭对数模

Twisted logarithmic modules of vertex algebras

Bojko Bakalov

摘要:

受对数共形域论和Gromov-Witten理论的启发,我们引入了顶点代数在任意(不一定是半单)自同构下的扭曲模的概念。它的主要特点是扭场涉及形式变量的对数。我们发展的理论,这种扭曲的模块,特别是,推导出Borcherds身份和交换子公式。我们详细研究仿射和海森堡顶点代数的例子。

英文摘要:

Motivated by logarithmic conformal field theory and Gromov-Witten theory, we introduce a notion of a twisted module of a vertex algebra under an arbitrary (not necessarily semisimple) automorphism. Its main feature is that the twisted fields involve the logarithm of the formal variable. We develop the theory of such twisted modules and, in particular, derive a Borcherds identity and commutator formula for them. We investigate in detail the examples of affine and Heisenberg vertex algebras.
