Inequalities of Ostrowski and Simpson type for mappings of two variables with bounded variation and applications. (English) Zbl 1275.26028

Summary: Two inequalities of Ostrowski type and Simpson type for mappings of two independent variables with bounded variation are established. A general inequality of trapezoid type is obtained. Applications to some special means and to a quadrature formula are given.
