Talk:Mathematical entropy

I've retracted my merge suggestion because Perelman's proof has nothing to do with Nash Entropy or shallow water equations, so I agree it is wise to have a page which gives summary of all these concepts. I'm going to work on expanding this page. JacobB 04:21, 23 December 2009 (EST)

I'm finding conflicting sources regarding Nash entropy - it's a concept I'm unfamiliar with and have had to research. Some sources seem to refer to it as a statistical phenomenon related to Nash equilibrium in many-player games. Others seem to describe it as a quantity related to the solution of the heat equation on some kinds of manifolds. JacobB 04:28, 23 December 2009 (EST)
