Approximation Properties of a Sequence of Linear and Positive Operators

摘要

In this paper we study the techniques of linear combinations starting from the studies made by H. Bohman (1952), P.L.Butzer (1953;), ( P.P. Korovkin (1953);), T. Popovici (1959;), D.D. Stancu respectively the results obtained by E. W. Cheney and A. Sharma S. Eisenberg and B. Wood M. Frentiu A. Lupas R. Martini We define the linear combinations for Favard-Szasz Sn operators we obtain different estimation of the remainder for Soperator.
