Abstract:

This paper considers a type of p-Laplace equation with dissipative gradient term. By means of suitable defined auxiliary functions and resulting the first-order differential inequalities, the conditions which ensure that blow-up occurs or does not occur are given. In addition, the lower bound for blow-up time is also determined if blow-up occurs.

Key words: Dissipative gradient, p-Laplace equation, Blow-up, Lower bound for the blow-up time
