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 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 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)] = ... -
ON RINGS OF QUOTIENTS OF SEMIPRIME Gamma-RINGS
(UNIV MISKOLC INST MATH, 2012)In this paper, we investigate the rings of quotients of a semiprime Gamma-ring. -
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) ... -
On Soft beta-Open Sets and Soft beta-Continuous Functions
(HINDAWI PUBLISHING CORP, 2014)We introduce the concepts soft beta-interior and soft beta-closure of a soft set in soft topological spaces. We also study soft beta-continuous functions and discuss their relations with soft continuous and other weaker ... -
On strong forms of completely irresolute functions
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)In this paper, we introduce new classes of functions which are called completely beta-irresolute functions, perfectly beta-irresolute functions and perfectly irresolute functions. We obtain their characterizations, their ... -
On Strongly Precontinuous Functions
(SPRINGER, 2008)In this paper, we give some characterizations of strongly precontinuous functions. Also we investigate some special properties of these function. -
On Sturm-Liouville operators with discontinuity conditions inside an interval
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006)In this study, transformation operator, some properties of kernel, properties of spectral characteristics and also uniquiness theorems for the inverse problems are studied for a class of Sturm-Liouville differential operators ... -
On super continuous multifunctions
(AKADEMIAI KIADO, 2003)We define upper (lower) super continuous multifunctions and obtain some characterizations and basic properties of such a multifunction. Also some relationships between the concept of super continuity and known concepts of ... -
On the boundary value problem for the Sturm-Liouville equation with the discontinuous coefficient
(WILEY-BLACKWELL, 2013)We consider a boundary value problem for the Sturm-Liouville equation with piecewise-constant leading coefficient. We prove that some integral representations for the solutions of the considered equation can be obtained ... -
On the centroid of prime semirings
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2013)We define and study the extended centroid of a prime semiring. We show that the extended centroid is a semifield and give some properties of the centroid of a right multiplicatively cancellable prime semiring. -
On the commutative neutrix product of distributions
(INDIAN NAT SCI ACAD, 1999)Let f, g be distributions in D' and let f(n)=f * delta(n), g(n)=g * delta(eta), where {delta(eta)} is a certain sequence converging to the Dirac delta-function. The neutrix product f square g is said to exist and be equal ... -

ON THE CONFLICTION BETWEEN RELIGION AND SCIENCE: A READING CENTERED ON COPERNICUS
(ERCIYES UNIV, 2017)Communication and interaction between religion and science is as old as the human history. This communication and interaction has occurred at times in the form of settlement and dialog and at other times in the form of ... -
