Towards the best constant in front of the Ditzian-Totik modulus of smoothness
Journal of Inequalities and Applications, 2016 We give accurate estimates for the constants K ( A ( I ) , n , x ) = sup f ∈ A ( I ) | L n f ( x ) − f ( x ) | ω σ 2 ( f ; 1 / n ) , x ∈ I , n = 1 , 2 , … , $$ K\bigl(\mathcal{A}(I), n, x\bigr)=\sup_{f\in\mathcal{A}(I)}\frac{|L_{n} f(x)-f(x)|}{\omega_ ...

Quantitative Estimates for Positive Linear Operators in terms of the Usual Second Modulus
Abstract and Applied Analysis, 2015 We give accurate estimates of the constants Cn(A(I),x) appearing in direct inequalities of the form |Lnf(x)-f(x)|≤Cn(A(I),x)ω2 f;σ(x)/n, f∈A(I), x∈I, and n=1,2,…, where Ln is a positive linear operator reproducing linear functions and acting on real ...

Generalized Jacobi–Weierstrass operators and Jacobi expansions
Journal of Inequalities and Applications, 2018 We present a realization for some K-functionals associated with Jacobi expansions in terms of generalized Jacobi–Weierstrass operators. Fractional powers of the operators as well as results concerning simultaneous approximation and Nikolskii–Stechkin ...
