Simultaneous 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 ...
متن کاملApproximation with modified Phillips operators
In the present paper, we study modified Phillips operators in simultaneous approximation. The operators discussed here are important as they have link with the well-known Szász operators. We estimate some direct results for the operators. c ©2017 All rights reserved.
متن کاملSimultaneous 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 کاملOn Simultaneous Approximation for Certain Baskakov Durrmeyer Type Operators
In the present paper, we study a certain integral modification of the well known Baskakov operators with the weight function of Beta basis function. We establish pointwise convergence, an asymptotic formula an error estimation and an inverse result in simultaneous approximation for these new operators.
