title: Sharp conditions for exponential and non-exponential uniform stabilization of the time-dependent damped wave equation
abstract: It is classical that uniform stabilization of solutions to the autonomous damped wave equation is equivalent to every geodesic meeting the positive set of the damping, which is called the geometric control condition. In this paper, it is shown that for time-dependent damping a generalization of the geometric control condition is equivalent to uniform stabilization at an exponential rate. Additionally, upper and lower bounds on non-exponential uniform stabilization rates are computed for damping
