Ostrowski Type Inequalities on Time Scales for Double Integrals

In this paper we first derive an Ostrowski type inequality on time scales for double integrals via ΔΔ-integral which unify corresponding continuous and discrete versions. We then replace the ΔΔ-integral by the ∇ ∇-, Δ∇-, and ∇Δ-integrals and get completely analogous results.
