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