New coincidence and common fixed point theorems
In this paper, we obtain some extensions and a generalization of a remarkable fixed point theorem of Proinov. Indeed, we obtain some coincidence and fixed point theorems for asymptotically regular non-self and self-maps without requiring continuity and ...

Common fixed point theorems in Menger spaces
We proved two common fixed point theorems for four self-mappings and two set-valued mappings with φ-contractive condition in a Menger space.

Common Fixed Point Theorems in a Complete 2-metric Space [PDF]
summary:In the present paper, we establish a common fixed point theorem for four self-mappings of a complete 2-metric space using the weak commutativity condition and $A$-contraction type condition and then extend the theorem for a class of ...

It is observed that certain theorems on common fixed points may be derived from a theorem on partially ordered sets.

Relational Meir-Keeler Contractions and Common Fixed Point Theorems
In this article, we prove some coincidence and common fixed point theorems under the relation-theoretic Meir-Keeler contractions in a metric space endowed with a locally finitely T-transitive binary relation.

Results on common fixed points [PDF]
We establish common fixed point theorems related with families of self mappings on metric spaces. Our results extend, improve, and unify the results due to Fisher (1977, 1978, 1979, 1981, 1984), Jungck (1988), and Ohta and Nikaido (1994).

Common Fixed-Point and Fixed-Circle Results for a Class of Discontinuous F-Contractive Mappings
The exploration of contractive inequalities which do not imply the continuity of the mapping at fixed points was an interesting open problem for quite some time.
