Abstract:

This paper is concerned with the time-asymptotically nonlinear stability of stationary solutions to the initial boundary value problem of hyperbolic equations with Cattaneo's law in one-dimensional half space. We construct the stationary solutions to such an initial boundary value problem and show their regularities. Moreover, by introducing a correction function, the asymptotic stability of the above stationary solutions under small initial perturbations is proved by using the $ L^2 $-energy method and Poincaré-type inequalities in half space.

Key words: Cattaneo's Law, initial-boundary value problem, stationary solutions, asymptotic stability, Poincaré-type inequalities
