Attractors for Damped Semilinear Wave Equations with a Robin--Acoustic Boundary Perturbation

Joseph L. Shomberg

Under consideration is the damped semilinear wave equation \[ u_{tt}+u_t-Δu + u + f(u)=0 \] on a bounded domain $\Omega$ in ${\mathbb{R}}^3$ with a perturbation parameter $\epsilon >0$…
