Construction of Baskakov-type operators by wavelets

Abstract

The purpose of this paper is to introduce a class of Baskakov-type operators by means of Daubechies’ compactly-supported wavelets. The new operators have the same moments as Baskakov operators in an arbitrarily chosen number. The rate of convergence of these operators is in connection with Lipschitz functions with respect to the second-order modulus of smoothness.
