Coupled fixed point results for nonlinear contraction mappings having a mixed monotone property in a partially ordered G-metric space due to Choudhury and Maity are extended and unified. In this paper, some corresponding coupled fixed point…

In 2008 Suzuki introduced C-condition for mappings which defined  on a subset of a Banach space and presented fixed point theorems. And in 2010 Khan and Suzuki gave a reich type convergence theorem for generalized nonexpansive mappings in u…

In 2012 Karapınar and Samet introduced the notion of α- contractive mappings and proved some well-known fixed point theorems. On the other hand in 2006 Mustafa and Sims gave the definition of G-metric space which is the generalization of me…

In 1964 Gahler introduced the theory of 2-normed spaces and then 1989 n-normed spaces was first defined by Misiak. Then some researcher found new results on n-inner product spaces and n-metric spaces. In 2001 Gunawan and Mashadi studied c…

In 1996 Kada, Suzuki and Takahashi defined the w-distance mappings on metric spaces and they proved fixed point theorems for w-distances. In 2008 Homidan, Ansari and Yao gave the Q-functions on quasi-metric space and they generalized the …
