Blow up property for viscoelastic evolution equations on manifolds with conical degeneration

arXiv:1602.02593

Abstract

This paper is concerned with the study of the nonlinear viscoelastic evolution equation with strong damping and source terms, described by \[u_{tt} - Δ_{\mathbb{B}}u + \int_{0}^{t}g(t-τ)Δ_{\mathbb{B}}u(τ)dτ+ f(x)u_{t}|u_{t}|^{m-2} = h(x)|u|^{p-2}u , \hspace{1 cm} x\in int\mathbb{B}, t > 0,\] where is a stretched manifold. First, we prove the solutions of problem {1.1} in cone Sobolev space admit a blow up in finite time for and positive initial energy. Then, we construct a lower bound for obtained blow up time under appropriate assumptions on data.
