Abstract:
In this talk, we present lower and upper bound estimates for the maximal existence time of solutions to the nonlinear heat equation, and solutions to a nonlinear parabolic system. We improve and extend some known results by considering a large class of initial data. Part of the results presented in this talk are from joint work with Fred B. Weissler.
