Feel free to post about mathematics in general, just keep the shitposting about 300k starting, CS, and stuff out of this thread. Let's actually talk about something meaningful this time.

Personally right now I am doing some reading in Kähler manifolds, in particular from the viewpoint of symplectic geometry.

I was wondering if anyone has any good books on differential equations as that has been a very abandoned subject for me since my undergraduate years. Maybe there is a good book in Springer's library? Thanks!
