The blow-up behavior of the solution to a semilinear equation with critical exponent {u(t) = Delta u + vertical bar u vertical bar(p-1)u in Omega x (0, T), u = 0 on partial derivative Omega x (0, T), u(., 0) = u0 on Omega is established. We obtain that if Omega is star-shaped about a is an element of Omega and n >= 3, p = n+2/n-2, then lim(t -> T)(T - t)(beta)u(a + y root T - t, t) exists and equals 0 or +/-kappa in L-loc(2) (R-n), where beta = 1/p-1, kapp...
