Propagation of Singularities and Some Inverse Problems in Wave Propagation
Propagation of Singularities and Some Inverse Problems in Wave Propagation
Abstract : We review a number of results relating the propagation of singularities for hyperbolic partial differential equations i.e. the persistence, or non-localization, of wave motion with well-posedness for some inverse problems of reflection type, such as arise for instance in seismology and ultrasonics. By far the most complete information …
