ABSTRACT.
In this paper, we present new definitions of multi-valued mappings in G- complete
G-metric spaces and establish a sharper sufficient condition for the existence of xed points by mak-
ing use of analysis technique. The results which are obtained improve, enrich, generalize and extend
many known results. Some examples are also given to demonstrate the application of our main results
