Abstract
The purpose of this paper is to extend Theorem 5 [18] to a S - metric space, without orbit-ally continuity, generalizing Theorem 4 [2], Theorems 1-4, 6-8 [11], Corollary 2.19 and 2.21 [23], Theorems 23, 24 [20], Theorems 3.2-3.4 [21] and to obtaining a Ćirić-Jotić-type result in S - metric spaces.
