We show that if N ≥ 11 and p > N - 2 (N - 1)1/2/(N - 4) - 2(N - 1)1/2 then there exist radial and positive solutions of (E) which blow up at x = 0, t = T < ∞ and such that GRAPHICS Precise asymptotics for these solutions near t = T are also obtainedjournal articlehttp://www.sciencedirect.com/science/journal/07644442metadata only access517.956.4Supercritical semilinear parabolic equationsradial and positive solutionsblow upEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
