Abstract

In this paper, we consider a class of nonlinear higher-order wave equation with logarithmic source and waek damping term u tt + (Δ) m u+u+ u t =uln | u | k in a bounded domain Ω R 3 . We establish a exponential decay of solutions.

Subject Areas

higher-order wave equation; logarithmic source term; energy decay
