Question on Gromov-Witten invariants when $A=0$

In this case, the J-holomorphic curves are all constant, so the evaluation pseudocycle is the tridiagonal $\{(x,x,x) : x\in M\}$. You take cycles $A_1,A_2,A_3$ Poincare dual to $a_1,a_2,a_3$ respectiv …

How not to use J-holomorphic curves

One classic thing to do is to take a sequence of holomorphic curves with a tangency condition and assume that the tangency condition still holds in the limit: if the limit is a multiple cover with a b …

Pseudo-holomorphic disk which is constant along boundary

Extend $u$ to get a $C^1$ pseudoholpmorphic map defined on $\mathbb{C}$ by setting $u$ constant outside the unit disc. It's $C^1$ because you know the derivative of $u$ along the unit circle vanishes …

Clarification on the ”neck stretching” applied to the base space of a Lefschetz fibration

For a start, the base of your Lefschetz fibration had better be a Riemann surface, or else it won't have any pseudoholomorphic sections for generic J (see for example Kruglikov's paper https://link.sp …
