**Duality for Nonconvex Approximation and Optimization**

During this monograph the writer offers the idea of duality for nonconvex approximation in normed linear areas and nonconvex worldwide optimization in in the community convex areas. distinctive proofs of effects are given, in addition to diversified illustrations. whereas some of the effects were released in mathematical journals, this is often the 1st time those effects look in ebook shape.

**Lectures on the automorphism groups of Kobayashi-hyperbolic manifolds**

Kobayashi-hyperbolic manifolds are an item of energetic examine in advanced geometry. during this monograph the writer offers a coherent exposition of contemporary effects on whole characterization of Kobayashi-hyperbolic manifolds with high-dimensional teams of holomorphic automorphisms. those category effects may be seen as complex-geometric analogues of these identified for Riemannian manifolds with high-dimensional isotropy teams, that have been commonly studied within the 1950s-70s.

G. Dassios and R. Kleinman, Low Frequency Scattering, Clarendon (2000). THE INVERSE SCATTERING PROBLEM FOR ANISOTROPIC MEDIA F. CAKONI AND D. edu We give a survey of recent results on the inverse scattering problem for anisotropic media including both uniqueness theorems and reconstruction algorithms. 1. Introduction The inverse electroniagnetic scattering problem for anisotropic media is significantly different than the corresponding problem for isotropic media. Further problems arise when an anisotropic dielectric medium is coated by a thin layer of a highly conducting material.

Assume that k2 is not an interior Neumann eigenvalue f o r the negative Laplacian in D . Let the density 'p be a solution to (9) and let z be a parametrization ( 6 ) of the boundary r.

A straightforward calculation using the asymptotic formulae for the fundamental solution CP given in shows that the far field pattern of V is K k [ z ,p]q.
