On Some Generalizations of Commuting Mappings [PDF]
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.

Some Common Fixed Points Theorems of Four Weakly Compatible Mappings in Metric Spaces
مجلة بغداد للعلوم, 2021 In this paper, we proved coincidence points theorems for two pairs mappings which are defined on nonempty subset in metric spaces by using condition (1.1). As application, we established a unique common fixed points theorems for these mappings by using

A description of linear mappings in semiprime rings with involution [PDF]
BIO Web of ConferencesThe main purpose of this paper is to descriptive the action of the linear mappings in semi-prime rings and prime ring with involution. More precisely, we establish some results for centralizer mappings (resp.

Neutrosophic Soft Fixed Points [PDF]
Neutrosophic Sets and Systems, 2020 . In a wide spectrum of mathematical issues, the presence of a fixed point (FP) is equal to the presence of a appropriate map solution. Thus in several fields of math and science, the presence of a fixed point is important.

Contractive mappings and common fixed point theorems in intuitionistic fuzzy metric spaces [PDF]
Journal of Hyperstructures, 2012 This paper deals with some issues of common fixed point theory involving two different types of intuitionistic fuzzy contractive mappings. Intuitionistic fuzzy Jungck’s common fixed point theorem (see, [1]) with respect to contraction defined in [8] and ...

Commuting Traces of Biadditive Mappings, Commutativity-Preserving Mappings and Lie Mappings [PDF]
Transactions of the American Mathematical Society, 1993 Using intricate but elementary calculations, the author obtains characterizations of Lie isomorphisms, Lie derivations, and other mappings of prime rings which extend a number of results in the literature. For the statement of all the results which follow, \(R\) and \(A\) are prime rings with neither of characteristic two and neither embedding in \(M_ ...

Hypercyclicity Properties of Commutator Maps [PDF]
Integral Equations and Operator Theory, 2016 We investigate the hypercyclic properties of commutator maps acting on separable ideals of operators. As the main result we prove the commutator map induced by scalar multiples of the backward shift operator fails to be hypercyclic on the space of compact operators on $\ell^2$. We also establish some necessary conditions which identify large classes of

On strong commutativity‐preserving maps [PDF]
International Journal of Mathematics and Mathematical Sciences, 2005 We identify some strong commutativity‐preserving maps on semiprime rings. Among other results, we prove the following. (i) A centralizing homomorphism f of a semiprime ring R onto itself is strong commutativity preserving. (ii) A centralizing antihomomorphism f of a 2‐torsion‐free semiprime ring R onto itself is strong commutativity preserving.
