Improvements of Euler-trapezoidal type inequalities with higher-order convexity and applications.
Inequalities between the quadrature operators and error bounds of quadrature rules.
Inequalities of Ostrowski type and applications in numerical integration.
Inequalities of Ostrowski-Grüss type and applications
Some new inequalities of Ostrowski-Grüss type are derived. They are applied to the error analysis for some Gaussian and Gaussian-like quadrature formulas.
Integral inequalities of the Ostrowski type.
Integration of polynomials
We prove that the only functions for which certain standard numerical integration formulas are exact are polynomials.
