15 صفحه اولApproximation of functions of two variables by certain linear positive operators
Abstract. We introduce certain linear positive operators and study some approximation properties of these operators in the space of functions, continuous on a compact set, of two variables. We also find the order of this approximation by using modulus of continuity. Moreover we define an rth order generalization of these operators and observe its approximation properties. Furthermore, we study ...
متن کاملApproximation of analytic functions of several variables by linear k-positive operators
We investigate the approximation of analytic functions of several variables in polydiscs by the sequences of linear k-positive operators in the Gadjiev sense.
متن کاملVORNICESCU, Neculae, APPROXIMATION OF FUNCTIONS OF TWO VARIABLES BY DISCRETE LINEAR POSITIVE OPERATORS
We introduce a class of discrete linear positive operators in the space of real continuous functions of two variables defined on the square [0,1] x [0,1]. These operators are associated to an arbitrary set of nodes
متن کاملOn the order of weighted approximation by positive linear operators
An estimation of approximation of continuous functions by positive linear operators in weighted norm using the weighted modulus of continuity is established. Application of the main result to the known Gadjiyev∗ -Ibragimov operators is given.
