UPPER BLOW-UP TIME AND LOWER GROW-UP RATE TO SOLUTION FOR A PSEUDO-PARABOLIC EQUATION
A. Toualbia, N. Barrouk

Abstract

In this paper, we consider a pseudo parabolic equation with weak-viscoelastic term, where the exponent in the source term is variable. Using a differential inequality technique, we prove that the solution with positive initial energy become unbounded at a finite time, and find an upper bound for this time. A lower grow-up rate of solution is also obtained.
