Abstract
The study of inverse results of approximation for the family of sampling Kantorovich operators in case of alpha-Holder function, 0 < alpha < 1, has been solved in a recent paper of some of the authors. However, the limit case of Lipschitz functions, i.e., when alpha = 1, in which standard methods fail, remained unsolved. In this paper, a solution of the above open problem of inverse approximation has been proposed.File in questo prodotto:
