Derivatives of integrating functions for orthonormal polynomials with exponential-type weights.
Direct and Converse Theorems for Generalized Bernstein-Type Operators
2000 Mathematics Subject Classification: 41A25, 41A27, 41A36.We establish direct and converse theorems for generalized parameter dependent Bernstein-type operators. The direct estimate is given using a K-functional and the inverse result is a strong converse inequality of type A, in the terminology of [2].
