引力后裔与高自旋曲线的模空间

Gravitational Descendants and the Moduli Space of Higher Spin Curves

Tyler J. Jarvis, Takashi Kimura, Arkady Vaintrob

摘要:

本文的目的是在$r$理论中引入一个新的公理(称为下降公理)--自旋上同调域论。这条公理解释了这个理论中引力后裔的起源。此外,下降公理直接隐含了消失公理,并根据虚类的乘法性来解释消失公理(在格罗莫夫-威滕不变量理论中没有先验的类似物)。我们证明了下降公理在凸的情况下成立,因此在亏格为零。

英文摘要:

The purpose of this note is introduce a new axiom (called the Descent Axiom) in the theory of $r$-spin cohomological field theories. This axiom explains the origin of gravitational descendants in this theory. Furthermore, the Descent Axiom immediately implies the Vanishing Axiom, explicating the latter (which has no a priori analog in the theory of Gromov-Witten invariants), in terms of the multiplicativity of the virtual class. We prove that the Descent Axiom holds in the convex case, and consequently in genus zero.
