Existence and Nonexistence of Global Solutions for Higher-Order Nonlinear Viscoelastic EquationsYaojun Ye (1) Zhejiang University of Science and Technology, Hangzhou, China
The initial-boundary value problem for some nonlinear higher-order viscoelastic equation with damping and source terms in a bounded domain is studied. The existence of global solutions for this problem is established by constructing a stable set in $H_0^l(\Omega)$ and the decay of energy based on a difference inequality due to M.~Nakao is obtained. Meanwhile, under suitable conditions on relaxation function~$g(\cdot)$ and the positive initial energy, it is proved that the solution blows up in the finite time and the lifespan estimates of solutions are also given.
Keywords: Nonlinear higher-order viscoelastic equation, initial-boundary value problem, global existence and nonexistence, decay estimate of solution
