Locally distributed control of wave equations with variable coefficients. (English) Zbl 1125.93379

Summary: For wave equations with variable coefficients on regions which are not necessarily smooth, we obtain a sufficient condition for the subregion on which the application of control will yield the exact controllability property by using piecewise multiplier method and Riemannian geometry method. Some examples are presented.
