Approximate Convex Function

Abstract

           In this paper, we present some results concerning of approximate convex function defined on a Banach space  These results were proposed by Huynh Van Ngai, Dinh The Luc, and Michel Théra, in [4]. However, most of them were not proved in full detail. In here, we present them in more detail with proofs.

Keywords: Approximate convex function,convex function, conjugate  function.
