General decay for a viscoelastic equation with time-varying delay in the boundary feedback condition

Abita Rahmoune

Vol. 9 (2021), No. 2, 127–142
Abstract

This paper is devoted to the study of the weak viscoelastic equation with memory and nonlinear time-varying delay in the boundary feedback condition. To this aim, we consider a mathematical model which describes the viscoelastic system with memory in a bounded domain. We establish the general decay estimate for the energy by introducing suitable Lyapunov functionals.
