Hi,
I'm a Physics student from Indonesia. Could anyone please give me proof
(in detail) of Poincare lemma ("All the exact forms is closed")?
Because
I haven't take Differential Geometry class. But I really interested.
If possible, could anyone also prove in detail that "the inverse of the
statement (Poincare lemma) is true locally, but not globally"?
I really appreciate if you'd like to help me on this problem. I guess
it's not a difficult problem for some of you. :)
Thank you very much.
Best regards,
Firdaus Prabowo
