A grad student of mathematics, studying Lie groups and representation theory.

Basically I am interested in geometry, but any topics will be interesting for me (actually I'm not good at algebra...).

I will often ask somewhat "ambiguous" questions. I think one can study details in textbooks but cannot study intuitions or important points of definition or theorem and I ask such questions. Please be kind, peers!
Of course, I always intend to clarify my questions or intention, so please notify me if my questions seem to have no points—sometimes they indeed do not have any points.
I'm also be careful not to ask "Primarily opinion-based" questions, but I can't see the difference between "good intuitional questions" and them yet, so before trying to close the questions, please notify me if some of my questions seem so.
cf. What is “the intuition behind a result”?
