Abstract

Abstract: This paper deals with some parabolic equations, where the reaction and the boundary flux are taken of some general forms. We study the explicit blow-up time estimates according to the different coupled relationship, including the lower and upper bounds of blow-up time for every dimension of space domains. As examples, the results could be used to so many completely coupled models.

Key words: parabolic equations, general coupled nonlinearity, boundary flux, blow-up time estimates
