Tropical refined curve counting from higher genera and lambda classes. (arXiv:1706.07762v1 [math.AG])

来源于:arXiv
Block and G\"ottsche have defined a $q$-number refinement of counts of tropical curves in $\mathbb{R}^2$. Under the change of variables $q=e^{iu}$, we show that the result is a generating series of higher genus log Gromov-Witten invariants with insertion of a lambda class. This gives a geometric interpretation of the Block-G\"ottsche invariants and makes their deformation invariance manifest. 查看全文>>
