Blowup versus global in time existence of solutions for nonlinear heat equations

Analysis of PDEs 2017-05-19 v2

Abstract

This note is devoted to a simple proof of blowup of solutions for a nonlinear heat equation. The criterion for a blowup is expressed in terms of a Morrey space norm and is in a sense complementary to conditions guaranteeing the global in time existence of solutions. The method goes back to H. Fujita and extends to other nonlinear parabolic equations.
