\(L^{p}\)-approximation \((p \geq 1)\) by Stancu-Kantorovich polynomials
Journal of Numerical Analysis and Approximation Theory, 2002 We establish direct and converse estimates for a generalized Kantorovich polynomial operator depending on a positive parameter.

Refined Estimates for the Equivalence Between Ditzian-Totik Moduli of Smoothness and K-Functionals [PDF]
The aim of this note is to study the magnitude of the constants in the equivalence between the first and secondorder Ditzian-Totik moduli of smoothness and related K-functionals.

Characterization of Hölder spaces corresponding to Ditzian-Totik modulus of smoothness
Approximation Theory and its Applications, 2000It is proved that the weighted Hölder spaces \(\Lambda_{\alpha, p}\) on the interval \([-1, 1]\) with the weight \(\varphi(x) = \sqrt {1-x^2}\) are linearly isomorphic to some sequence spaces. The isomorphism is given by the coefficients of functions with respect to a system of orthonormal splines with knots uniformly distributed according to the ...
