We also prove that two real functions f and g, defined on a real interval [a, b], satisfy for all x, y ∈ [a, b] and t ∈ [0, 1] iff there exists a reciprocally strongly convex function h : [a, b] → R such that f (x) ≤ h(x) ≤ g(x) for all x ∈ [a, b]. Finally, we obtain an approximate convexity result for reciprocally strongly convex functions; namely we prove a stability result of Hyers-Ulam type for this class of functions.

In this paper, we give generalization of the Jensen's inequality by using definition of convex functions on n–coordinates. Results given in [5] are particular cases of results given here.

We give some inequalities of Jensen type and Lazhar type for the class of harmonically and strongly reciprocally convex functions.

We also prove that two real functions f and g, defined on a real interval [a, b], satisfy f (xy/( tx + (1 − t)y)) ≤ tg (y) + (1 − t)g (x) − ct(1 − t) (1/ x − 1/ y)^ 2 , for all x, y ∈ [a, b] and t ∈ [0, 1] iff there exists a reciprocally strongly convex function h : [a, b] → R such that f (x) ≤ h (x) ≤ g (x) for all x ∈ [a, b].
