Best Approximation by Linear Superpositions (Approximate Nomography) (Translations of Mathematical Monographs) - Hardcover

Inhaltsangabe

Addressed to graduate students and mathematicians working in approximation theory and constructive function theory, and to functional analysts working in deep and non-trivial applications. Deals with problems of approximating continuous or bounded functions of several variables by the linear superposition of functions that are from the same class and have fewer variables. The main topic is the space of linear superpositions considered as a subspace of the space of continuous functions on a compact space. Investigates such properties as density, closedness, and proximality. Translated from an unpublished Russian manuscript. No index. Member prices are $41 for individuals and $55 for institutions.
