Abstract

Consider the semilinear heat equation (see (1.1)) with reaction term u^p, p>1. We construct solutions that blow up at a finite time T, according to a variety of specific asymptotic behaviors. These blow-up patterns are unstable. The corresponding solutions have an arbitrary large number of local maxima, collapsing for t=T.
