**Abstract:**

In this paper we establish some basic inequalities for -Ψ-convex functions when Ψ = − ln. Applications for power functions and weighted arithmetic mean and geometric mean are also provided.

**Keywords:**

Convex functions, special convexity, weighted arithmetic and geometric means, logarithmic function.
