Inequalities for some iterated linear operators and their applications in approximation theory
Some inequalities for the ”derivatives” of iterated linear operators will be presented, which will be applied for the investigation of degrees of approximation. Thus, with the application of the Laplacian we improve some classical results concerning the Jackson type estimate, the inverse theorem as...
