Approximation by Combination of Operators of Summation-Integral Type

The linear positive operators are saturated by order O(1/n). We discuss two combination techniques, iterative and linear to significantly improve this order. The central theorems i.e. direct, inverse and saturation have been discussed. The Bezier variant of a linear operators has been introduced. The last topic is error estimate by an integrated Baskakov-type operator for the functions of the bounded variation.

Approximation by positive operators have been interesting topic for last three decades. This book deals with techniques of improvement of degree of approximation which is small in these methods. A. R. Gairola is PhD from IIT Roorkee and is Associate Professor at Graphic Era University, Dehradun
