On the exponential time-decay for the one-dimensional wave equation with variable coefficients

Anton Arnold, Sjoerd Geevers, Ilaria Perugia +1

We consider the initial-value problem for the one-dimensional, time-dependent wave equation with positive, Lipschitz continuous coefficients, which are constant outside a bounded r…
