Blow-up time for a semilinear parabolic equation with variable reaction

Authors: THEODORE KOUASSI BONI, REMI KOUADIO KOUAKOU

Abstract: In this paper, we address the solution of a semilinear heat equation with variable reaction subject to Dirichlet boundary conditions and nonnegative initial datum. Under some assumptions, we show that the solution of the above problem blows up in a finite time, and its blow-up time goes to that of the solution of a certain differential equation. Finally, we give some numerical results to illustrate our analysis.

Keywords: Semilinear parabolic equation, blow-up, numerical blow-up time
