New Characterization for Nonlinear Weighted Best Simultaneous Approximation

Abstract

This paper is concerned with the problem of a wide class of weighted best simultaneous approximation in normed linear spaces, and it establishes a new characterization result for the class of approximation by virtue of the notion of simultaneous regular point.
