Random attractors for stochastic delay wave equations on $ \mathbb{R}^n $ with linear memory and nonlinear damping

A non-autonomous stochastic delay wave equation with linear memory and nonlinear damping driven by additive white noise is considered on the unbounded domain \begin{document}$ \mathbb{R}^n $\end{document} . We establish the existence and uniqueness of a random attractor \begin{document}$ \mathcal{A} $\end{document} that is compact in \begin{document}$ C{([-h, 0];H^1(\mathbb{R}^n))}\times C{([-h, 0];L^2(\mathbb{R}^n))}\times L_\mu^2(\mathbb{R}^+;H^1(\mathbb{R}^n)) $\end{document} with \begin{document}$ 1\leqslant n \leqslant 3 $\end{document} .
