Quotient of the hyperbolic plane with respect to commutator group of $\pi_1(\Sigma_g)$
For fun: Finite Jacob ladder can be seen here cambridgeblog.org/2013/01/intotheintrogamesandmathematic.

Quotient of the hyperbolic plane with respect to commutator group of $\pi_1(\Sigma_g)$
@ BS: interesting, I had never heard of such terminologies. Is there any somewhat recent book discussing this sort of things!

Quotient of the hyperbolic plane with respect to commutator group of $\pi_1(\Sigma_g)$
Of course it is infinite, but it should be still describeable in terms on number of ends and genus; e.g. a pair of pants is genus zero with 3 ends. In this case, I feel it should be a genus 0 curve with infinity many ends dictated by the type of free graph.

Thanks Seirios: But what is rank of it? Can we say that? at least for g=2?

Lagrangian fibration on Schoen's CalabiYau 3fold
There is not much known about the existence of smooth Special Lagrangian fibrations. See 2013 or 2008 survey of Gross on SYZ.

Symplectic sum and Symplectic cut
Thanks, I finally wrote it myself. At least in one direction, the main point is the Exercise 3.36 of McDuffSalamon

genus one GromovWitten invariants of CalabiYau 3folds
Thanks for sharing, I appreciate it. People can go through the link and study his answer. I found his answer somewhat problematic, I may suggest some reviews to him later. There is also some recent talk by Aleksey Zinger in Simons center which is related to the subject, I would share the link some time later.

On Lerman's description of symplectic cut
Thanks for the example, I need to think about it.
