Some results on near-rings with generalized derivations
(2005)
n merkezi Z olan bir sağ asal near-halka, f : N $\rightarrow$TV tanımlı d ile ilgili bir genelleştirilmiş türev olsun. Bu durumda: (i) Eğer $f^2(N) = 0$ ise f = 0 dır. (ii) Eğer $f(N)\subset Z$ ise N değişmeli bir halkadır, ...
INVERSE NODAL PROBLEM FOR A STURM-LIOUVILLE OPERATOR WITH DISCONTINUOUS COEFFICIENT
(2017)
Inverse nodal problem for SturmñLiouville equation with discontinuity coe¢ cient is studied. A uniqueness theorem and an algorithm for recovering the coe¢ cients of the problem from a known sequence related ...
On ?-(?,?)-Lie ideals of ?-prime rings with derivation
(2018)
Let R be a ??prime ring with characteristic not 2, U be a nonzero ??(?,?)?Lie ideal of R and d be a nonzero derivation of R. Suppose ?,? be two automorphisms of R such that ?d = d?,?d = d? and ? commutes with ?,?,d. In the ...
Tri-additive maps and permuting tri-derivations
(2005)
Öztürk [7] de asal ve yarı-asal halkalar üzerinde permuting tri-türevlerle ilgili bazı sonuçlar ispatladı. Biz s-unital halkalar üzerinde çarpık-kommuting veya çarpık-merkezleyen izli tri-toplamsal dönüşümleri çalıştık ve ...
Effect of New Water-Soluble Dendritic Phthalocyanines on Human Colorectal and Liver Cancer Cell Lines
(2017)
Human hepatocellular carcinoma (HepG2) cells and colorectal adenocarcinoma (DLD-1) cells were treated with the synthesized water soluble phthalocyanine derivatives to understand the effect of the compounds both on colorectal ...
LIPOLYTIC ACTIVITY OF LACTIC ACID BACTERIA ISOLATED FROM TURKISH PASTIRMA
(2018)
Lipases are widely distributed in nature and catalyze the hydrolysis of mono, di and tri acyl glycerols to liberate free fatty acids and glycerol. Various microorganisms produce lipases either alone or together with esterase. ...
On Jordan generalized derivations in gamma rings
(2004)
In this study, We define a generalized derivation and a Jordan generalized derivation on F-rings and show that a Jordan generalized derivation on some F-rings is a generalized derivation.
Notes on near-ring ideals with (?, ? )-derivation
(2015)
In the present paper, we extend some well known results concerning derivations of prime near-rings in [4], [5] and [13] to (σ, τ )−derivations and semigroup ideals of prime near-rings. 2000 AMS ...
A COUPLED FIXED POINT RESULT IN PARTIALLY ORDERED PARTIAL METRIC SPACES THROUGH IMPLICIT FUNCTION
(2013)
In this manuscript, we discuss the existence of coupled fixed points inthe context of partially ordered metric spaces through implicit relationsfor mappings F : X× X -> X such that F has the mixed monotoneproperty. ...
Compactness of the set of trajectories of the control systemdescribed by a Urysohn type integral equation
(2017)
The control system with integral constraint on the controls is studied, wherethe behavior of the system by a Urysohn type integral equation is described. Itis assumed that the system is nonlinear with respect to the state ...
