Block and Göttsche have defined a q-number refinement of counts of tropical curves in $$\mathbb {R}^2$$R2. Under the change of variables $$q=e^{iu}$$q=eiu, 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-Göttsche invariants and makes their deformation invariance manifest.

从较高属和 lambda 类计数的热带细化曲线

Block 和 Göttsche 在 $$\mathbb {R}^2$$R2 中定义了热带曲线计数的 q 数细化。在变量 $$q=e^{iu}$$q=eiu 的变化下,我们表明结果是生成一系列插入 lambda 类的更高属对数对数 Gromov-Witten 不变量。这给出了 Block-Göttsche 不变量的几何解释,并使它们的变形不变性明显。
