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_ ...

Compatible mappings and common fixed points

International Journal of Mathematics and Mathematical Sciences, 1986
A generalization of the commuting mapping concept is introduced. Properties of this “weakened commutativity” are derived and used to obtain results which generalize a theorem by Park and Bae, a theorem by Hadzic, and others.

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.

Canonical commutation relation preserving maps [PDF]

Journal of Physics A: Mathematical and General, 2001
We study maps preserving the Heisenberg commutation relation $ab - ba=1$. We find a one-parameter deformation of the standard realization of the above algebra in terms of a coordinate and its dual derivative. It involves a non-local ``coordinate'' operator while the dual ``derivative'' is just the Jackson finite-difference operator.

The commuting block maps problem [PDF]

Transactions of the American Mathematical Society, 1979
A block map is a map f : { 0 , 1 } n → { 0 , 1 } f:\,{\{ {\text {0}},\,{\text {1}}\} ^n}\, \to \,\{ 0,\,1\} for some

Common Fixed Point Theorem for Non-Self Mappings Satisfying Generalized Ćirić Type Contraction Condition in Cone Metric Space

Fixed Point Theory and Applications, 2010

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

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 ...

Integrability and Fusion Algebra for Quantum Mappings [PDF]

, 1992
We apply the fusion procedure to a quantum Yang-Baxter algebra associated with time-discrete integrable systems, notably integrable quantum mappings. We present a general construction of higher-order quantum invariants for these systems.

A description of linear mappings in semiprime rings with involution [PDF]

BIO Web of Conferences
The 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.
