Some remarks on coupled, tripled and n-tupled coincidence and fixed points theorems in ordered abstract metric spaces
(Pushpa Publishing House, 2015) Fadail, Zaid Mohammed; Ahmad, Abd Ghafur Bin; Rad, Ghasem Soleimani; Öztürk, Vildan; Radenović, Stojan
In this paper, we introduce the concept of monotone mappings and monotone mapping with respect to other mapping to obtain some coupled, tripled and n-tupled coincidence and fixed point results in partially ordered abstract metric spaces. Our results generalize, extend, complement and improve various comparable results in the existing literature. The examples are given to illustrate the usability of our results.
Some remarks on fixed point results of b₂ -metric spaces
(Pushpa Publishing House, 2015) Fadail, Zaid Mohammed; Ahmad, Abd Ghafur Bin; Öztürk, Vildan; Radenović, Stojan
In this paper, we consider, discuss and generalize some recent fixed point results for mappings in ₂-metric and b₂ -metric spaces established by Mustafa et al. [31]. By using one new lemma all our results are with much shorter proofs. One example shows that our generalizations are genuine.
