Generalized limits and sequence of matrices
(Birkhauser Verlag AG, 2019)Banach has proved that there exist positive linear regular functionals on m such that they are invariant under shift operator where m is the space of all bounded real sequences. It has also been shown that there exists ... -
Almost unit-clean rings
(Editura Academiei Romane, 2019)A ring R is almost unit-clean provided that every element in R is equivalent to the sum of an idempotent and a regular element. We prove that every ring in which every zero-divisor is strongly ?-regular is almost unit-clean ... -
On the F-contraction properties of multivalued integral type transformations
(Institute of Mathematics NAS of Ukraine, 2019)The main purpose of this work is to extend the properties of multivalued transformations to the integral type transformations and to obtain the existence of fixed points under F-contraction. In addition, the results of ... -
Preservice Mathematics Teachers’ Understanding of and Abilities to Differentiate Proportional Relationships from Nonproportional Relationships
(Springer Netherlands, 2019)This study investigated preservice middle school mathematics teachers’ (PSTs) understanding of proportional and nonproportional relationships and their abilities to differentiate these relationships from each other. The ... -
Korovkin type approximation theorems via power series method
(Springer International Publishing, 2019)In this paper we consider power series method which is also member of the class of all continuous summability methods. The power series method includes Abel method as well as Borel method. We investigate, using the power ... -
Diagnosing Preservice Teachers’ Understanding of Statistics and Probability: Developing a Test for Cognitive Assessment
(Springer Netherlands, 2019)This study investigates preservice middle school mathematics teachers’ understanding of statistics and probability and provides a cognitive diagnostic assessment of their strengths and weaknesses on these subjects. A ... -

(Isik University, 2019)The aim of this paper is to obtain a new theorem dealing with absolute matrix summability factors. © 2019, Işik University, Department of Mathematics. -
A nil approach to symmetricity of rings
(Allahabad Mathematical Society, 2018)We introduce a weakly symmetric ring which is a generalization of a symmetric ring and a strengthening of both a GWS ring and a weakly reversible ring, and investigate properties of the class of this kind of rings. A ring ... -
Hypotheses testing for fuzzy robust regression parameters
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)The classical least squares (LS) method is widely used in regression analysis because computing its estimate is easy and traditional. However, LS estimators are very sensitive to outliers and to other deviations from basic ... -
Harmonic curvatures and generalized helices in E-n
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)In n-dimensional Euclidean space E-n, harmonic curvatures of a non-degenerate curve defined by Ozdamar and Haci-salihoglu [Ozdamar E, Hacisalihoglu HH. A characterization of Inclined curves in Euclidean n-space. Comm Fac ... -
Boundedness of the Maximal, Potential and Singular Operators in the Generalized Morrey Spaces
(SPRINGER, 2009)We consider generalized Morrey spaces Mp,w (R(n)) with a general function. w(x, r) defining the Morrey- type norm. We find the conditions on the pair (w(1), w(2)) which ensures the boundedness of the maximal operator and ... -
Non-self-adjoint boundary-value problem with discontinuous density function
(JOHN WILEY & SONS LTD, 2010)We determine spectrum and principal functions of the non-self-adjoint differential operator corresponding to 1-D non-self-adjoint Schrodinger equation with discontinuous density function, provide some sufficient conditions ... -
Neural networks approach for determining total claim amounts in insurance
(ELSEVIER SCIENCE BV, 2009)In this study, we present an approach based on neural networks, as an alternative to the ordinary least squares method, to describe the relation between the dependent and independent variables. It has been suggested to ... -
(L-p, L-q) Boundedness of the fractional maximal operator associated with the Dunkl operator on the real line
(TAYLOR & FRANCIS LTD, 2010)On the real line, the Dunkl operators are differential-difference operators associated with the reflection group Z(2) on R. In this paper, we obtain necessary and sufficient conditions on the parameters for the boundedness ... -
Characterizations of slant helices in Euclidean 3-space
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2010)In this paper we investigate the relations between a general helix and a slant helix. Moreover, we obtain some differential equations which they are characterizations for a. space curve to be a slant helix. Also, we obtain ... -
