On fuzzy h-ideals in hemirings
(2004)The fuzzy setting of a left h-ideal in a hemiring is constructed, and basic properties are investigated. Using a collection of left h-ideals of a hemiring S, fuzzy left h-ideals of S are established. The notion of a finite ... -
On generalized statistical convergence of double sequences via ideals
(2012)The concept of statistical convergence is one of the most active area of research in the field of summability. Most of the new summability methods have relation with this popular method. In this paper we generalize the ... -
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. -
On inverse problem for singular sturm-liouville operator with discontinuity conditions
(2014)In this study, properties of spectral characteristic are investigated for singular Sturm-Liouville operators in the case where an eigen parameter not only appears in the differential equation but is also linearly contained ... -
ON LIE IDEALS AND GENERALIZED DERIVATIONS OF *-PRIME RINGS
(UNIV MISKOLC INST MATH, 2013)Let (r, *) be a 2-torsion free *-prime ring with involution * and center Z (R), U a nonzero square closed *-Lie ideal of R. An additive mapping F W R! R is called a generalized derivation if there exits a derivation d WR ... -
On Lie ideals with generalized derivations
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2006)Let R be a prime ring with characteristic different from 2, let U be a nonzero Lie ideal of R, and let f be a generalized derivation associated with d. We prove the following results: (i) If a is an element of R and [a, f ... -
On near-ring ideals with (?, ?)-derivation
(2007)Let N be a 3-prime left near-ring with multiplicative center Z, a (?, ?)-derivation D on N is defined to be an additive endomorphism satisfying the product rule D(xy) = ?(x)D(y) + D(x)?(y) for all x, y ? N, where ? and ? ... -
On perfectly ?-irresolute functions
(2010)In this paper, some results concerning properties of perfectly ?- irresolute functions and their relationships with other types of functions between topological spaces are obtained. Some new characterizations of connected ... -
On Prime and Semiprime Near-Rings with Generalized Derivation
(NATL INQUIRY SERVICES CENTRE PTY LTD, 2010)Let N be a left near-ring and S be a nonempty subset of N. A mapping F from N to N is called commuting on S if [F(x),x] = 0 for all x S. The mapping F is called strong commutativity preserving (SCP) on S if [F(x),F(y)] = ... -

(2012)In this paper, we investigate the rings of quotients of a semiprime ?-ring. © 2012 Miskolc University Press. -
On semiderivations of *-prime rings
(SOC PARANAENSE MATEMATICA, 2015)Let R be a *-prime ring, with involution * and center Z(R). An additive mapping F : R -> R is called a semiderivation if there exists a function g : R -> R, such that (i) F(xy) =F(x)g(y) + xF(y) = F(x)y + g(x)F(y) and (ii) ... -
