comment 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/into-the-intro-games-and-mathematic.

comment 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!

comment Simply connected pencils
Thanks Jason; for curves, I used to think this should be true!

comment 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 describe-able 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.

comment Quotient of the hyperbolic plane with respect to commutator group of $\pi_1(\Sigma_g)$
Thanks Seirios: But what is rank of it? Can we say that? at least for g=2?

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

comment 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 McDuff-Salamon

comment genus one Gromov-Witten invariants of Calabi-Yau 3-folds
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.

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