The weakly logarithmically convex (concave) functions and their properties

Sun Qian-gao

Abstract

Aim To discuss the weakly logarithmically convex(concave) functions and their properties.Methods The analytical and mathematical induction methods are used.Results Some equivalent descriptions for weakly logarithmically convex(concave) functions are given.Conclusion A weakly logarithmically convex(concave) function has some good properties,and is closely related to a normal convex(concave) function.
