3. Error bounds for a class of quadrature formulas.

Author

Sofonea, Florin, Acu, Ana Maria, Rafiq, Arif, and Barbosu, Dan

Subjects
*GAUSSIAN quadrature formulas, *NUMERICAL integration, *DIFFERENTIABLE functions, *MATHEMATICS theorems, *CHEBYSHEV polynomials, *MATHEMATICAL models
Abstract

A class of optimal quadrature formulas in sense of minimal error bounds are obtained. The estimations of remainder term will be given in terms of variety of norms, from an inequality point of view. Some improvements and generalizations of some results from literature will be considered. [ABSTRACT FROM AUTHOR]

4. On Bullen's and related inequalities.

Author

Acu, Ana Maria and Gonska, Heiner

Subjects
*MATHEMATICAL inequalities, *APPROXIMATION theory, *MATHEMATICAL functions, *MATHEMATICS theorems, *MATHEMATICAL models
Abstract

The estimate in Bullen's inequality will be extended for continuous functions using the second order modulus of smoothness. A different form of this inequality will be given in terms of the least concave majorant. Also, the composite case of Bullen's inequality is considered. [ABSTRACT FROM AUTHOR]
