Property C, that is, completeness of the set of products of some solutions to Sturm-Liouville equations is proved. Several uniqueness theorems for various inverse scattering problems are obtained in a very simple way with ...
From the scattering data one finds the support function or the principal curvatures of the surface of a reflecting obstacle. From either of these data the surface is effectively reconstructed.
It is proved that any potential of a single layer v is identically equal to a potential of a double layer w in the bounded domain, D, and a necessary and sufficient condition for v≡w in Ω=R³/D, the exterior domain, is given.
Many-body quantum-mechanical scattering problem is solved asymptotically when
the size of the scatterers (inhomogeneities) tends to zero and their number tends to
infinity.
A method is given for calculation of the number ...
Combining an asymptotic method and computational modelling the authors propose a method for creating materials with the desired electrodynamical characteristics, in particular, with a desired refraction
coefficient. The ...
Formulas are derived for solutions of many-body wave scattering problems by small
particles in the case of acoustically soft, hard, and impedance particles embedded in
an inhomogeneous medium. The limiting case is ...

A class of infinite-dimensional dissipative dynamical systems is defined for
which the slow invariant manifolds can be calculated. Large-time behavior of
the evolution of such systems is studied.
A review of the author’s results is given. Inversion formulas and stability results
for the solutions to 3D inverse scattering problems with fixed energy data are obtained. Inversion of exact and noisy data is considered. ...
A novel approach to an old symmetry problem is developed. A new proof is given for the following symmetry problem, studied earlier: if Δu = 1 in D ⊂ R[superscript 3], u = 0 on S, the boundary of D, and u[subscript N] = ...
