通过Givental群作用于上同调场论的BCOV理论

BCOV theory via Givental group action on cohomological field theories

S. Shadrin

AI总结:

本研究借助Givental群在上同调场论上的作用,诠释了此前由Losev等人基于BCOV相关工作拓展构造的、对应任意循环Hodge dGBV代数的完整后代势,使该势满足所有泰希米勒方程的结论变得直观。

摘要:

在先前的论文(arXiv:0704.1001)中,Losev、本人与Shneiberg针对任意循环Hodge dGBV代数构造了一个完整的后代势。该构造拓展了Barannikov与Kontsevich提出的WDVV方程解的构造,其基础是Bershadsky、Cecotti、Ooguri与Vafa的早期论文。在本文中,我们借助Givental群在上同调场论上的作用,给出了该完整后代势的一种诠释。尤其是,它满足所有泰希米勒方程这一事实变得显而易见。

英文摘要:

In a previous paper (arXiv:0704.1001), Losev, me, and Shneiberg constructed a full descendant potential associated to an arbitrary cyclic Hodge dGBV algebra. This contruction extended the construction of Barannikov and Kontsevich of solution of the WDVV equation, based on the earlier paper of Bershadsky, Cecotti, Ooguri, and Vafa. In the present paper, we give an interpretation of this full descendant potential in terms of Givental group action on cohomological field theories. In particular, the fact that it satisfies all tautological equations becomes a trivial observation.
