Common fixed point theorems on non-complete partial metric spaces

Nonlinear Analysis, 2013
In the peresent paper, we give a common fixed point theorem for four weakly compatible mappings on non-complete partial metric spaces. Some supporting examples are provided.

Note on 'Common fixed point theorem for weakly compatible multi-valued mappings satisfying strongly tangential property' [PDF]

Mathematica Moravica, 2016
In our paper [1], the existence and uniqueness of a common fixed point for multi valued mappings was given, hence in this note we point out to no uniqueness of common fixed point in theorem 3.1, corollary 3.1 and corollary 3.2.

Common Fixed Point for Three Pairs of Self-Maps Satisfying Common (E.A) Property in Generalized Metric Spaces

Abstract and Applied Analysis, 2013
Using the concept of common (E.A) property, we prove a common fixed point theorem for three pairs of weakly compatible self-maps satisfying a new contractive condition in the framework of a generalized metric space.

Common Fixed Point for Weakly Compatible Mappings in Menger Spaces

International Journal of Computer Applications, 2011
In this paper the concept of weakly compatible map in complete Menger PM space has been applied to prove common fixed point theorem via an implicit relation by using the common property (E.A). Mathematics Subject Classification 47H10, 54H25.

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Fixed Point for Weakly Compatible Maps Satisfying Generalized Contraction Principle

Journal of Scientific Research, 2011
We prove common fixed point theorems for a pair of weakly compatible mappings satisfying a generalized contraction principle by using a control function and implicit relation. We also establish invariant approximation result as an application of the result.Keywords: Common fixed point; Weakly compatible maps; Control function; Invariant approximation.©

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

Advanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

On Multistep Iterative Scheme for Approximating the Common Fixed Points of Contractive-Like Operators

International Journal of Mathematics and Mathematical Sciences, 2010
We introduce the Jungck-multistep iteration and show that it converges strongly to the unique common fixed point of a pair of weakly compatible generalized contractive-like operators defined on a Banach space.
