Some fixed point theorems for compatible maps

International Journal of Mathematics and Mathematical Sciences, 1993
A collection of fixed point theorems is generalized by replacing hypothesized commutativity or weak commutativity of functions involved by compatibility.

COINCIDENCE POINTS OF WEAKLY COMPATIBLE MAPPINGS [PDF]

Bulletin of the Korean Mathematical Society, 2008
We present coincidence points and common fixed point re- sults for (f, g)-contractive mapping and (f, g)-nonexpansive mappings. Our results generalize and complement various known results existing in the literature.

Poles of Archimedean zeta functions for analytic mappings

, 2011
In this paper, we give a description of the possible poles of the local zeta function attached to a complex or real analytic mapping in terms of a log-principalization of an ideal associated to the mapping.

Generalised Common Fixed Point Theorems of A-Compatible and S-Compatible Mappings [PDF]

American Journal of Applied Mathematics and Statistics, 2013
In this paper we prove a common fixed point theorem of four self mappings satisfying a generalized inequality using the concept of A-compatible and S-compatible mappings. Our result generalizes many earlier related results in the literature.

Compatibility support mappings in effect algebras [PDF]

Mathematica Slovaca, 2012
Abstract We give a characterization of subsets of effect algebras, that can be embedded into a range of an observable. To give this characterization, we introduce a new notion of compatibility support mappings.

On Some Generalizations of Commuting Mappings

Abstract and Applied Analysis, 2012
It is shown that occasionally JH operators as well as occasionally weakly biased mappings reduce to weakly compatible mappings in the presence of a unique point of coincidence (and a unique common fixed point) of the given maps.

Menelaus' theorem, Clifford configurations and inversive geometry of the Schwarzian KP hierarchy

, 2001
It is shown that the integrable discrete Schwarzian KP (dSKP) equation which constitutes an algebraic superposition formula associated with, for instance, the Schwarzian KP hierarchy, the classical Darboux transformation and quasi-conformal mappings ...

TVS-cone metric spaces as a special case of metric spaces [PDF]

, 2012
There have been a number of generalizations of fixed point results to the so called TVS-cone metric spaces, based on a distance function that takes values in some cone with nonempty interior (solid cone) in some topological vector space. In this paper we

Some Common Best Proximity Point Results in Neutrosophic Complete Metric Spaces

Mathematics
In this research article, we prove the existence and uniqueness of common best proximity points for a given class of discontinuous mappings. For that, we have introduced the notions of neutrosophic proximally compatible mappings, neutrosophic proximally ...
