Abstract

<p style='text-indent:20px;'>In this paper, we analyze a semilinear abstract damped wave-type equation with time delay. We assume that the delay feedback coefficient is variable in time and belongs to <inline-formula><tex-math id="M1">\begin{document}$ L^1_{loc}([0, +\infty)). $\end{document}</tex-math></inline-formula> Under suitable assumptions, we show well-posedness and exponential stability for <i>small</i> initial data. Our strategy combines careful energy estimates and continuity arguments. Some examples illustrate the abstract results.</p>
