Abstract: This paper deals with the initial-boundary value problem for a class of higher-order nonlinear wave equation with strong dissipative term in a bounded domain. We prove the existence of global solutions for this problem by constructing a stable set in H0m(Ω) and give the exponential decay estimate. Meanwhile, the blow-up result of solution in the unstable set is also obtained if the initial energy is positive.

Key words: Nonlinear higher-order wave equation, Initial-boundary value problem, Strong dissipative term, Global solution, Exponential decay
