| 中文摘要: |
| 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. |
| 英文摘要: |
| 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. |
