Global smoothness preservation by singular integrals
Proyecciones (Antofagasta), 2018 Here is established that the well-known singular integrals of Picard, Poisson-Cauchy and Gauss- Weierstrass fulfill the "global smoothness preservation" property. J. e., they "ripple" less than the function they are applied on, that is producing a nice approximation to the unit. The associated inequalities are sharp.

Global smoothness and approximation by generalized discrete singular operators [PDF]
Journal of Numerical Analysis and Approximation Theory, 2014 In this article we continue with the study of generalized discrete singular operators over the real line regarding their simultaneous global smoothness preservation property with respect to \(L_{p}\) norm for \( 1\leq p\leq \infty ,\) by involving ...

Transformation of the second order modulus by positive linear operators
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015 We obtain estimates for the transformation of the second order modulus of continuity by positive linear operators which satisfy certain conditions, which are common to a large class of approximation operators.

The second order modulus revisited: remarks, applications, problems
Journal of Numerical Analysis and Approximation TheorySeveral questions concerning the second order modulus of smoothness are addressed in this note. The central part is a refined analysis of a construction of certain smooth functions by Zhuk and its application to several problems in approximation theory,
