Am descoperit o teorema, unde pot sa o public pe drepturi de autor?
DAU FUNDA!

Daca realmente ai descoperit ceva valoros, scrie un articol in engleza si trimite-l la una din revistele indexate ISI. Ti se vor respecta drepturile de autor si vei intra in competitie pentru premii nationale si internationale. De exemplu: http://www.springer.com/mathematics/journal/11511

Crede-ma nu ai descoperit nimic. Alte toreme pe lumea asta nu exista filozofule. Macar ai indraznit sa cauti pe internet teorema ta? Crede-ma nu ai unde. Doara citeste si daca nu stii traduce.
This is currently far too vague to answer. What cand of theory is it? Do you have evidence for your theory? What is your educational background in physics? Are you in contact with professors who might be able to give you posting access to arXiv.org e-Print archive?

If you don't have extensive training in physics, your theory is almost certainly not ready for publication. The first step would be to make sure that your theory is reasonable, then worry about where to publish it.

In terms of checking whether it's reasonable, Quora is a decent bet. There are enough physicists around that they should hopefully be able to give you some quick feedback. I'll warn you, though, that the vast majority of the "theories" of physics that non-physicists come up with make absolutely no sense and contradict known experimental results. So, you should try not to get too attached to your idea, until you've run it by someone who can give you informed feedback!
