Abstract
A theorem concenrning the fixed points of non-continuos self-mappings in metric spaces is given in this paper, with conditions different from the usual fixed point theorems, by using the notion of r.g.i. function (property weaker than l.s.c.). Some corollaries and two examples of applications are given.File allegati a questo prodotto
