Stability of the solution to inverse obstacle scattering problem
inverse obstacle scattering problem math
2010/11/1
It is proved that if the scattering amplitudes at a fixed wavenumber for two obstacles from a certain large class of obstacles differ a little, than the obstacles differ a little. Error estimate is g...
On the wave operators and Levinson's theorem for potential scattering in R^3

2010/12/13
The paper is a presentation of recent investigations on potential scattering in R3. We advocate a new formula for the wave operators and deduce the various outcomes that follow
from this formula. A t...
Uniqueness theorems for inverse obstacle scattering in Lipschitz domains
Uniqueness theorems inverse obstacle scattering in Lipschitz domains
2010/11/1
An inverse problem of finding an obstacle and the boundary condition on its surface from the fixed-energy scattering data is studied. A new method is developed for a proof of the uniqueness results. T...
