Exact boundary observability for nonautonomous quasilinear wave equations
arXiv:0907.1760
Abstract
By means of a direct and constructive method based on the theory of semiglobal solution, the local exact boundary observability is shown for nonautonomous 1-D quasilinear wave equations. The essential difference between nonautonomous wave equations and autonomous ones is also revealed.
