Voronovskaya type results and operators fixing two functions

AM Acu, AI Măduţa, I Rasa - Mathematical Modelling and Analysis, 2021 - jest.vgtu.lt
The present paper deals with positive linear operators which fix two functions. The transfer of
a given sequence (L n) of positive linear operators to a new sequence (K n) is investigated …

Iterated Boolean sums of Bernstein type operators

T Acar, A Aral, I Raşa - Numerical Functional Analysis and …, 2020 - Taylor & Francis
The approximation of functions using linear positive operators is affected by saturation. The
quality of approximation offered by iterated Boolean sums increases with the regularity of the …

Some results for the inverse of a Bernstein–Schnabl type operator

AM Acu, M Heilmann, I Rasa - Analysis and Mathematical Physics, 2023 - Springer
Abstract We consider a Bernstein–Schnabl operator L n which commutes with the derivative
and consequently can be represented as a differential operator with constant coefficients …
