چکیده
Abstract In this note, we spotlight a generalization of Weierstrass integral operators introduced by Eugeniusz Wachnicki. The construction involves modified Bessel functions. are correlated with diffusion equation. Our main result consists in obtaining the asymptotic expansion derivatives any order Wachnicki’s operators. All coefficients explicitly calculated, and distinct expressions provided for analytical

Simultaneous Approximation Terms for Multi-dimensional Summation-by-Parts Operators
This paper continues our effort to generalize summation-by-parts (SBP) finite-difference methods beyond tensor-products in multiple dimensions. In this work, we focus on the accurate and stable coupling of elements in the context of discontinuous solution spaces. We show how penalty terms — simultaneous approximation terms (SATs) — can be adapted to discretizations based on multi-dimensional SB...
متن کاملGlobal smoothness preservation and simultaneous approximation by multivariate discrete operators
In this article we study the multivariate generalized discrete singular operators defined on R , N ≥ 1, regarding their simultaneus global smoothness preservation property with respect to Lp norm for 1 ≤ p ≤ ∞, by using higher order moduli of smoothness. Furthermore, we study their simultaneous approximation properties. Mathematics Subject Classification (2010): 26A15, 26D15, 41A17, 41A25, 41A2...
متن کاملOn simultaneous approximation by iterated Boolean sums of Bernstein operators
The paper presents upper estimates of the error of weighted and unweighted simultaneous approximation by the Bernstein operators and their iterated Boolean sums. The estimates are stated in terms of the Ditzian-Totik modulus of smoothness or appropriate K-functionals. AMS classification: 41A10, 41A17, 41A25, 41A28, 41A35, 41A36.
متن کاملSimultaneous Approximation for the Phillips-bézier Operators
We study the simultaneous approximation properties of the Bézier variant of the well known Phillips operators and estimate the rate of convergence of the Phillips-Bézier operators in simultaneous approximation, for functions of bounded variation.
متن کاملSimultaneous approximation for the Phillips operators
May [4] estimated some direct and inverse results for certain combinations of these operators. Very recently Finta and Gupta [1] studied some direct and inverse results for the second-order Ditzian-Totik modulus of smoothness. The rates of convergence in ordinary approximation for function of bounded variation for these operators and similar types of operators were estimated in [2, 3, 7]. Very ...
