摘要: In this paper, we consider the integro-differential equation $u_{tt}-M(\|\nabla u\|^{2}_{2})\Delta u+ \int_{0}^{t} g(t-\tau)\Delta u(\tau)\, d\tau+ u_{t}=f(u)$ , $(x,t)\in\Omega\times(0,T)$ with initial and Dirichlet boundary conditions. Under suitable assumptions on functions g data, a blow-up result arbitrary positive energy is established.
