Some fixed point theorems for generalized contractive mappings in complete metric spaces

Fixed Point Theory and Applications, 2015
We introduce new concepts of generalized contractive and generalized α-Suzuki type contractive mappings. Then, we obtain sufficient conditions for the existence of a fixed point of these classes of mappings on complete metric spaces and b-complete b ...

Some Comments on Edelstein’s Fixed Point Theorems in ν-Generalized Metric Spaces [PDF]

, 2018
We study deeply two fixed point theorems in n-generalized metric spaces. The two theorems are generalizations of the famous, Edelstein’s fixed point theorem in compact metric ...

Random fixed point theorems for asymptotic 1-set contraction operators

International Journal of Mathematics and Mathematical Sciences, 2002
Random fixed point theorems for condensing, 1-set contraction selfless are known. But no random fixed point theorem for more general asymptotic 1-set contraction selfmaps is yet available.

Some fixed point theorems in b-metric-like spaces

, 2015
In this work, some fixed point and common fixed point theorems are investigated in b-metric-like spaces. Some of our results generalize related results in the literature.

Unique Fixed Point Theorems for Generalized Contractive Mappings in Partial Metric Spaces

, 2015
We establish some unique fixed point theorems in complete partial metric spaces for generalized weakly -contractive mappings, containing two altering distance functions under certain assumptions.
