Degree axiom for P1 or P2

I am getting stuck on equation (7.33) on p. 192 of Cox-Katz's Mirror Symmetry and Algebraic Geometry. This concerns the degree of a cohomology class used as input for a Gromov-Witten invariant. Let $X$...

Generalization of Gromov-Witten theory counting surfaces, 3-folds, etc

I don't work on the Gromov-Witten theory, but I find that I need to study the following problem, which seems to be similar to the Gromov-Witten theory: Let $X$ be a variety and $\alpha_{1}, \cdots, \...

Divisibility of Gromov-Witten invariants

We know if a smooth complex projective variety $X$ is Fano, when the insertions of Gromov-Witten invariants are integral cohomology classes $\alpha_i \in H^*(X; {\mathbb Z})$, in genus zero the (...

Taubes' SW$\Rightarrow$ Gr

I am reading Taubes' paper on SW$\Rightarrow$ Gr and lost in some analysis, can anyone help me to see how to get equation 2.19 from equation 2.18? Is this some version of Kato for the Laplacian?

Enumerative or Gromov-Witten invariants from derived category of coherent sheaves

Let $X$ be a smooth projective toric Fano surface over $\mathbb{C}$. Suppose I have a nice presentation of $D^b_{Coh}(X)$ given by a full, strong exceptional collection $\mathcal{E} = \{E_i\}_{i\in I}$...
