Abstract
We extend the definitions of ∇−convex and completely monotonic functions for two variables. Some general identities of Popoviciu type integrals ∫ P(y)f(y)dy and ∫ ∫ P(y, z)f(y, z)dydz are deduced. Using obtained identities, positivity of these expressions are characterized for higher order ∇−convex and completely monotonic functions. Some applications in terms of generalized Cauchy means and exponential convexity are given.
