局部实Gromov-Witten不变量的分裂公式

Splitting formulas for the local real Gromov-Witten invariants

Penka Georgieva, Eleny-Nicoleta Ionel

摘要:

受Gopakumar-Vafa猜想3-folds的真实版本的启发,作者在[GI]中引入了与实曲线上的局部3-folds相关的局部实Gromov-Witten不变量的概念。本文证明了这些不变量在目标退化下的分裂公式。它是用在[GI]表明,不变量产生了一个2维克莱因TQFT和证明本地版本的真正Gopakumar-Vafa猜想。

英文摘要:

Motivated by the real version of the Gopakumar-Vafa conjecture for 3-folds, the authors introduced in [GI] the notion of local real Gromov-Witten invariants associated to local 3-folds over Real curves. This article is devoted to the proof of a splitting formula for these invariants under target degenerations. It is used in [GI] to show that the invariants give rise to a 2-dimensional Klein TQFT and to prove the local version of the real Gopakumar-Vafa conjecture.
