Abstract: In this paper we consider a stabilization problem for an abstract wave equation with delay and a Kelvin–Voigt damping. We prove an exponential stability result for appropriate damping coefficients. The proof of the main result is based on a frequency-domain approach.

Keywords: internal stabilization, Kelvin–Voigt damping, abstract wave equation with delay
