On left ideals of prime rings with generalized derivations
(2005)
In this paper the author considers a prime ring R with characteristic different from two and extends some well known results concerning derivations of prime rings to the generalized derivation f : R —> R ...
Lie Ideals of Semiprime Rings with Generalized Derivations
(2018)
Let R be a 2-torsion free semiprime ring, U a noncentral square-closed Lie ideal of R. A map F:R?R is called a generalized derivations if there exists a derivation d:R?R such that F(xy) = F(x)y + xd(y) for all x,y?R. In ...
Notes on commutativity of prime rings with generalized derivation
(2009)
Bu çalışmada, [2] ve [8] makalelerinde genelleştirilmiş türevli asal halkalar için elde edilen sonuçlar, sıfırdan farklı bir Lie ideal için incelenmiştir.
On a theorem of Posner for 3-prime near-rings with $(\sigma,\tau)$ derivation
(2007)
The analog of Posner's theorem on the composition of two derivations in prime rings is proved for 3-prime near-rings with $d_1 a (\sigma,\tau)$-derivation and $d_2$ a derivation.
RESULTS ON ?CENTRALIZERS OF PRIME AND SEMIPRIME RINGS WITH INVOLUTION
(2017)
Let R be a prime or semiprime ring equipped with an involutionand be an automorphism of R: An additive mapping T : R R iscalled a left (resp. right)T (xy) =of R. A left (resp. right) Jordanmapping such that T x2= T (x) (x ...
ON THE EXISTENCE OF "-OPTIMAL TRAJECTORIES OF THE CONTROL SYSTEMS WITH CONSTRAINED CONTROL RESOURCES
(2017)
The control system described by a Urysohn type integral equationis considered. It is assumed that the admissible control functions are chosenfrom the closed ball of the space Lp; p > 1;with radius r and centered atthe ...
A new view of fuzzy gamma rings
(2010)
The aim of this paper is to define a new kind of fuzzy gamma ring. So the concepts of fuzzy gamma ring, fuzzy ideal, fuzzy quotient gamma ring, and fuzzy gamma homomorphism are introduced.
On generalized derivations of prime near-rings
(2006)
Let N be a 2-torsion free prime near-ring with center Z, (f; d) and (g, h) two generalized derivations on N. In this case: (i) If f([x; y]) = 0 or f([x; y]) = $\pm$[x; y] or $f^2(x)\in Z$ for all x; y $\in$ N, then N is a ...
Economic Freedom Index Calculation Using FCM
(2018)
The Index of Economic Freedom is an annual index and ranking created by The Heritage Foundation and The Wall Street Journal in 1995 to measure the degree of economic freedom in the world's nations. There are many kinds of ...
