Keywords: Baskakov operators Mastroianni operators Bernstein operators Localization results Simultaneous approximation Meyer-König and Zeller operators Bleimann, Butzer and Hahn operatorsIn this paper we study localization results for classical sequences of linear positive operators that are particular cases of the generalized Baskakov/Mastroianni operators and also for certain class of composite operators that can be derived from them by means of a suitable transformation. Amongst these composite operators we can find classical sequences like the Meyer-König and Zeller operators and the Bleimann, Butzer and Hahn ones. We extend in different senses the traditional form of the localization results that we find in the classical literature and we show several examples of sequences with different behavior to this respect.
