Abstract

The concept of weakly-Chebyshev subspace is defined by Mohebi and Mazaheri. In this paper, we can replace the function by a function f with least conditions, and also we shall define f-weakly Chebyshev subspaces similar to weakly Chebyshev subspaces and we shall obtain the same theorems and results at about these subspaces.

Keywords

f-boundedly compact set, f-Chebyshev, f-proximinal, f-weakly Chebyshev.
