摘要: We review a selection of extremal problems to do with constrained approximation in certain Banach spaces holomorphic functions, including the classical Hardy and Paley-Wiener spaces. In many cases solutions are best interpreted terms linear operators. Applications under discussion systems identification, signal processing, inverse for partial differential equations, operator theory presented.
