Research Abstract

We study the critical exponent of the blowing up of the solution for a reaction-diffusion system and the life span of the solution for a reaction-diffusion equation. The objective of the study is to understand the mechanism of the blowing up of the solution. In this study, we employ the matrix representing the nonlinearity of the equations. The matrix makes the analysis simple, and helps us to understand the mechanism of the blowing up.
