tt^(*)几何的等单值τ函数

Isomonodromic τ Function of tt^(*)Geometry

在本文中,作者定义了Landau-Ginzburg B-模型中的tt^(*)几何结构对应的等单值τ函数.基于Getzler,Dubrovin-Zhang在亏格1的Gromov-Witten理论的部分工作,作者将所定义的τ函数和物理上给出的亏格1的Landau-Ginzburg B-模型的生成函数联系起来.

In this paper,the author defines the isomonodromic tau function of tt^(*)geometry in the Landau-Ginzburg B model.Inspired by the Dubrovin-Zhang’s work on the one-loop approximation,the author relates the τ function to the primary genus 1 generating function of Landau-Ginzburg B model.
