A major problem in solving multiwave inverse problems is the presence of critical points where the collected data completely vanishes. The set of these critical points depends on the choice of the boundary conditions and can be directly determined from the data itself. To our knowledge, in most existing stability results, the boundary conditions are assumed to be close to a set of complex geometrical optical solutions where the critical points can be avoided. We establish in the present work new weighted stability estimates for an electroacoustic inverse problem without assumptions on the presence of critical points. These results show that the Holder stability far from the critical points deteriorates near these points to a logarithmic stability. |
