作者： Tern, Pedro, l  pez_Dían, Miguel (Facultad de Ciencias, Universidad de oviedo, C/Calvo Sotelo, s/n 33007 oviedo Spain) (Communicated by ZHANG Shi_sheng) Facultad de Ciencias Universidad de Oviedo C/Calvo Sotelo Oviedo Spain

A way to extend operators in spaces of continuous functions to spaces of continuous set_valued functions is proposed. This extension is developed through the Steiner selections of the set_valued functions. Their properties and characteristics of the convergence of sequences of operators of this class are studied. In Part Ⅱ of this series some applications to approximation theory will be shown.
