A blowup result in a multidimensional semilinear thermoelastic system

Abstract

In this work, we consider a multidimensional semilinear system of thermoelasticity and show that the energy of any weak solution blows up in finite time if the initial energy is negative. This work generalizes earlier results in [5] and [8].
