Titolo: On some nonlinear diffusions on manifolds
Abstract: I shall discuss recent results on the porous medium and fast
diffusion equations on negatively curved manifolds. Among the main
problems considered I mention detailed asymptotics of positive
solutions, that depend in a crucial way on curvature assumptions.
Uniqueness of solutions in suitable classes is another critical issue,
and I shall discuss how in the fast diffusion case this turns out to be
related to parabolicity, a purely linear concept.
