On Biharmonic Hypersurfaces in Semi-Euclidean Spaces
(AMER INST PHYSICS, 2018)In this paper we study biharmonic hypersurfaces of semi-Euclidean spaces. We consider the Chen conjecture which states that the only biharmonic submanifolds of Euclidean spaces are the minimal ones. In particular, we obtain ... -
On Centralizing and Strong Commutativity Preserving Maps of Semiprime Rings
(SPRINGER, 2015)We study some properties of centralizing and strong commutativity preserving maps of semiprime rings. -
ON COMMUTATIVITY OF PRIME NEAR-RINGS WITH MULTIPLICATIVE GENERALIZED DERIVATION
(ANKARA UNIV, FAC SCI, 2019)In the present paper, we shall prove that 3 near-ring N is commutative ring, if any one of the following conditions are satis.ed: (i) f(N) subset of Z; (ii) f([x; y]) = 0; (iii) f([x; y]) = +/-[x; y]; (iv) f([x; y]) = ... -
ON COMMUTATIVITY OF SEMIPRIME RINGS WITH GENERALIZED DERIVATIONS
(SCIENTIFIC PUBL-INDIA, 2009)Let R be an associative ring. An additive mapping f : R -> R is called a generalized derivation if there exists a derivation d : R -> R such that f (xy) f (x)y + xd(y), for all x, y E R. In this paper, we explore the ... -
On discontinuous Dirac operator with eigenparameter dependent boundary and two transmission conditions
(SPRINGEROPEN, 2016)In this paper, we consider a discontinuous Dirac operator with eigenparameter dependent both boundary and two transmission conditions. We introduce a suitable Hilbert space formulation and get some properties of eigenvalues ... -

ON IMPULSIVE STURM-LIOUVILLE OPERATORS WITH COULOMB POTENTIAL AND SPECTRAL PARAMETER LINEARLY CONTAINED IN BOUNDARY CONDITIONS
(SPRINGER, 2011)The Sturm-Liouville problem with linear discontinuities is investigated in the case where an eigenparameter appears not only in a differential equation but also in boundary conditions. Properties and the asymptotic behavior ... -
On impulsive Sturm-Liouville operators with singularity and spectral parameter in boundary conditions
(SPRINGER, 2013)We study properties and the asymptotic behavior of spectral characteristics for a class of singular Sturm-Liouville differential operators with discontinuity conditions and an eigenparameter in boundary conditions. We also ... -
On Integral Representation for Solution of Generalized Sturm-Liouville Equation with Discontinuity Conditions
(SOC PARANAENSE MATEMATICA, 2015)In this paper, some properties of kernel and integral representation of Jost solution are studied for Sturm-Liouville operator with diffusion potential and discontinuity on the half line. -
