On 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.

Recently, Govil and Gupta [7] studied some approximation properties for the operators Bnpf, ̈q and estimated local results in terms of modulus of continuity. Generalization of the operators (1.1) with parameter ...
متن کاملApproximation by Generalized Srivastava–gupta Operators Based on Certain Parameter
In the year 2003, Srivastava and Gupta [18] introduced a general family of summation-integral type operators which include some well-known operators as special cases. They estimated the rate of convergence for functions of bounded variation. After that several researchers studied different approximation properties of these important general form of operators, we mention some of them as [10,19, ...
متن کاملApproximation Algorithms for Certain NetworkImprovement
We study budget constrained network upgrading problems. Such problems aim at nding optimal strategies for improving a network under some cost measure subject to certain budget constraints. Given an edge weighted graph G = (V; E), in the edge based upgrading model, it is assumed that each edge e of the given network also has an associated function ce(t) that speciies the cost of upgrading the ed...
متن کاملLocal Approximation Estimates for a Certain Family of Summation-Integral Type Operators
In 1988, Felten obtained local and global approximation theorems for positive linear operators. In the last decade, Finta studied direct local and global approximation theorems for Baskakov type operators and SzaszMirakian type operators. In the present paper, we establish some local approximation estimates for a new family of beta operators, by using Ditzian-Totik modulus of smoothness.
