Coincidence points in uniform spaces [PDF]

International Journal of Mathematics and Mathematical Sciences, 1993
In this note, we give a coincidence point theorem in sequentially complete Hausdorff uniform spaces. Our result reduces to a result of Acharya [1].

Coincidence points of mappings in Banach spaces [PDF]

Fixed Point Theory, 2018
In this article we prove an existence theorem for coincidence points of mappings in Banach spaces. This theorem generalizes the Kantorovich fixed point theorem.

Common Coincidence Points and Common Fixed Points in Fuzzy Semi-Metric Spaces

Mathematics, 2018
We propose the so-called fuzzy semi-metric space in which the symmetric condition is not assumed to be satisfied. In this case, there are four kinds of triangle inequalities that should be considered.

On coincidence and common fixed points of nearly densifying mappings [PDF]

International Journal of Mathematics and Mathematical Sciences, 2000
Coincidence and common fixed point theorems for certain new classes of nearly densifying mappings are established. Our results extend, improve, and unify a lot of previously known theorems.

Coupled coincidence points for monotone operators in partially ordered metric spaces [PDF]

Fixed Point Theory and Applications, 2011
Using the notion of compatible mappings in the setting of a partially ordered metric space, we prove the existence and uniqueness of coupled coincidence points involving a (ϕ, ψ)-contractive condition for a mappings having the mixed g-monotone ...

Coincidence Best Proximity Points of Proximal Berinde G-Contractions

Journal of Mathematics
Recently, a concept of proximal Berinde contractions was introduced and applied to prove the existence of coincidence best proximity points in metric spaces. In this article, we established a new approach to show that these results can be obtained from a

On Strong Coupled Coincidence Points of g-Couplings and an Application

Journal of Function Spaces, 2018
The purpose of this paper is to prove the existence and uniqueness of a strong coupled coincidence point of F:X×X→X and g:X→X, involving Banach and Chatterjea type g-couplings.

Coincidence and fixed points of nonlinear Hybrid contractions [PDF]

International Journal of Mathematics and Mathematical Sciences, 1989
In this Der, we show the existence of solutions of functional equations fx∈sx∩tx and x=fx∈sx∩Tx under certain contraction and asymptotic regularity conditions, where f, S and T are single-valued and multl-valued mappings on a metric space, respectively ...
