Presents a wide range of problems connected with rational approximations of numbers and analytic functions; these problems touch on many topics in contemporary analysis, such as analytic functions, orthogonal polynomials, spectral theory of operators, and potential theory.
Presents a unified exposition of the main areas and methods of the theory of Kleinian groups and the theory of uniformization of manifolds.... Læs mere
