On Simultaneous Weakly-Chebyshev Subspaces

Author(s)

Abstract

In this paper, we shall introduce and characterize simultaneous quasi-Chebyshev (and weakly-Chebyshev) subspaces of normed spaces with respect to a bounded set $S$ by using elements of the dual space.

Keywords:

dual space best simultaneous approximation simultaneous quasi-Chebyshev subspace simultaneous weakly-Chebyshev subspace.
