Abstract
We consider the Cauchy problem where u 0 ∈C 0 ℝ N the space of all continuous functions on ℝ N that decay to zero at infinity and p is supercritical in the sense that N≥11 and pge N224N+8sqrtN1/N2N10 We first examine the domain of attraction of steady states and also of general solutions in a class of admissible functions In particular we give a sharp condition on the initial function u 0 so that the solution of the above problem converges to a given steady state Then we consider the asymptotic behavior of global solutions bounded above and below by classical steady states such solutions have compact trajectories in C 0 ℝ N under the supremum norm Our main result reveals an interesting possibility the solution may approach a continuum of steady states not settling down to any particular one of them Finally we prove the existence of global unbounded solutions a phenomenon that does not occur for Sobolevsubcritical exponents
