TI - A Note on The Best Approximation in Spaces of Affine Functions
TT -
N2 - The proximinality of certain subspaces of spaces of bounded affine functions is proved. The results presented here are some linear versions of an old result due to Mazur. For the proofs we use some sandwich theorems of Fenchel's duality theory.
