comment commuting subsets in a group
I mean for any $(t_1, t_2)\in K\times K$. As usual, they can be the same or different.

comment what is the definition of “two parallel copies of a surface S”
thanks, so it is kind of disjoint union, the resulting surface has genus 2g?

comment question on subgroup of compact group
thanks a lot for your answer! The subgroup I am interested in is closed, coming from fixed point of a group element in some group acting on this $G$. My knowledge on topological groups, especially lie groups is almost zero..., I apologize for the inaccuracy. Any books on this stuff to recommend? Thanks again!

comment question on subgroup of compact group
@CameronWilliams, I mean $K\leq G$ is of finite index if the left coset $G/H$ is finite. Equivalently, if the Haar measure of $K$ is nonzero. Maybe there is better name for this?
