I think that classification of math into subforums on this math forum is highly incomplete. For instance, suppose that one wants to discuss number theory or discrete mathematics. Is this supposed to belong to general math? What if one wants to discuss subtleties of the last Fermat theorem or of Ramsey theory, does it really belong to general math? Or computation theory, like P=NP conjecture, on which subforum should this be discussed? Or discrete dynamical systems? Since they are discrete, the differential equations subforum does not seem appropriate. Or algebraic geometry, should it be considered a branch of differential geometry? It is also quite unnatural to have logic and set theory in the same subforum with probability and statistics. Am I the only one who thinks that math forum should be significantly reorganized?
