Note on Lie ideals with symmetric bi-derivations in semiprime rings
(Springer, 2023)Let R be a semiprime ring, U a square-closed Lie ideal of R and D : R x R -> R a symmetric bi-derivation and d be the trace of D. In the present paper, we prove that the R contains a nonzero central ideal if any one of the ... -
On a Classification of Almost C(α)-Manifolds
(Hindawi, Journal of Mathematics, 2022)In this paper, pseudosymmetric and Ricci pseudosymmetric almost C(/alpha)-manifold are studied. For an almost C(/alpha)-manifold, Riemann pseudosymmetric, Riemann Ricci pseudosymmetric, Ricci pseudosymmetric, projective ... -
On the robustness of the integrable trajectories of the control systems with limited control resources
(Polish Academy of Sciences, 14.09.2023)The control system described by Urysohn type integral equation is considered where the system is nonlinear with respect to the phase vector and is affine with respect to the control vector. The control functions are chosen ... -
RECONSTRUCTION OF A STURM-LIOUVILLE OPERATOR WITH SOME NONLOCAL BOUNDARY CONDITIONS
(2023)In the present paper, a Sturm-Liouville equation and two nonlocal boundary conditions which are generalized versions of Bitsadze-Samarskii-type conditions are considered. The main goal of this paper is to obtain the ... -
SOFT SET-VALUED MAPPINGS AND ITS APPLICATION IN DECISION MAKING PROBLEMS
(2021)In this paper, we introduce the notion of a set-valued mapping on soft classes and study several properties of images and inverse images of soft sets supported by examples and counterexamples. Finally, these notions have ... -
SOME ALGEBRAIC PROPERTIES OF GENERALIZED q− CESARO MATRIX C_g (q)
(2023)In this paper, we define the generalized q-Cesaro matrix by using generalized Cesaro matrix and q-Cesaro matrix. We investigate normality, self-adjointedness and Hilbert-Schmidt properties of generalized q-Cesaro matrices. -
Some Classification Theorems and Endomorphisms in New Classes
(MDPI, 2023)Let ℧ be a prime ring of char(℧) not equal 2 with its center Z. This article introduces new classes of endomorphisms and investigates how they relate to antiautomorphisms of prime rings and the commutativity of prime rings. ... -
Some identities involving multiplicative semiderivations on ideals
(Hacettepe Journal of Mathematics & Statistics, 2021)Let R be a prime ring and I be a nonzero ideal of R. A mapping d : R → R is called a multiplicative semiderivation if there exists a function g : R → R such that (i) d(xy) = d(x)g(y)+xd(y) = d(x)y +g(x)d(y) and (ii) ... -

Subdivisions of the spectra for cesaro, rhaly and weighted mean operators on c(0),c and l(P)
(SPRINGER INTERNATIONAL PUBLISHING AG, 2011)There are many different ways to subdivide the spectrum of a bounded linear operator; some of them are motivated by applications to physics (in particular, quantum mechanics). In this study, the relationship between the ... -
