Fixed point results for generalized chatterjea type contractive conditions in partially ordered G-metric spaces
(
Hindawi Publishing Corporation
, 2014 , Article)
In the framework of ordered G -metric spaces, fixed points of maps that satisfy the generalized Chatterjea type contractive conditions are obtained. The results presented in the paper generalize and extend several well ...
