We present an overview of some results about characterization of compactness in which the concept of approximation scheme has had a role. In particular, we present several results that were proved by the second author, jointly with Luther, a decade ago, when these authors were working on a very general theory of approximation spaces. We then introduce and show the basic properties of a new concept of compactness, which was studied by the first author in the eighties, by using a generalized…

The theory of compact linear operators acting on a Banach space has a classical core and is familiar to many. Perhaps less known is the characterization theorem of Terzioglu for compact maps. This…

COMPACTNESS AND GENERALIZED APPROXIMATION SPACES

ABSTRACT We show that generalized approximation spaces can be used to describe the relatively compact sets of Banach spaces. This leads to compactness and convergence criteria in the approximation…

Generalized approximation spaces and applications

In the paper we generalize the theory of classical approximation spaces to a much wider class of spaces which are defined with the help of best approximation errors. We also give some applications.…

On strict inclusion relations between approximation and interpolation spaces

Approximation spaces, in their many presentations, are well known mathematical objects and many authors have studied them for long time. They were introduced by Butzer and Scherer in 1968 and,…

A Generalization of N-Widths

This paper is a study of the n-widths defined by Kolmogorov. In section I we give definitions of n-widths of a set in a Banach space and n-widths of an operator acting between Banach spaces. Several…

Constructive Approximation

This paper works on [-1, 1 ] and obtains Markov-type estimates for the derivatives of polynomials from a rather wide family of classes of constrained polynomes and results turn out to be sharp.
