P-properties in Near-rings
(INST TEKNOLOGI BANDUNG, 2019)In this paper, assuming that N is a near-ring and P is an ideal of N, the P-center of N, the P-center of an element in N, the P-identities of N are defined. Their properties and relations are investigated. It is shown that ... -
ALMOST UNIT-CLEAN RINGS
(EDITURA ACAD 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 pi-regular is almost unit-clean ... -
On The F-Contractıon Propertıes Of Multıvalued Integral Type Transformatıons
(INST MATHEMATICS, 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 ... -
A NEW RESULT FOR WEIGHTED ARITHMETIC MEAN SUMMABILITY FACTORS OF INFINITE SERIES INVOLVING ALMOST INCREASING SEQUENCES
(ANKARA UNIV, FAC SCI, 2019)In this paper, a known theorem dealing with weighted mean summability methods of non-decreasing sequences has been generalized for vertical bar A, p(n); delta vertical bar(k) summability factors of almost increasing ... -
THE DIMENSION OF PRODUCTS OF n HOMOGENEOUS COMPONENTS IN FREE LIE ALGEBRAS
(ANKARA UNIV, FAC SCI, 2019)Let L be a free Lie algebra of finite rank r >= 2 over a field F and we let L-mi denote the degree m(i) homogeneous component of L. Ralph Stohr and Micheal Vaughan-Lee derived formulae for the dimension of the subspaces ... -
Fractional maximal function and its commutators on Orlicz spaces
(SPRINGER BASEL AG, 2019)In this paper, we find necessary and sufficient conditions for the boundedness of fractional maximal operator M on Orlicz spaces. As an application of this results we consider the boundedness of fractional maximal commutator ... -
On Medium *-Clean Rings
(SPRINGER BASEL AG, 2019)A *-ring R is called a medium *-clean ring if every element in R is the sum or difference of an element in its Jacobson radical and a projection that commute. We prove that a ring R is medium *-clean if and only if R is ... -
MEASURE OF NONCOMPACTNESS IN THE STUDY OF SOLUTIONS FOR A SYSTEM OF INTEGRAL EQUATIONS
(INDONESIAN MATHEMATICAL SOC, 2019)In this work, we prove the existence of solutions for a tripled system of integral equations using some new results of fixed point theory associated with measure of noncompactness. These results extend the results in some ... -
Generalized fractional maximal and integral operators on Orlicz and generalized Orlicz-Morrey spaces of the third kind
(SPRINGER, 2019)In the present paper, we will characterize the boundedness of the generalized fractional integral operators I rho and the generalized fractional maximal operators M rho on Orlicz spaces, respectively. Moreover, we will ... -
Regularity for generators of invariant subspaces of the Dirichlet shift
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2019)Let D denote the classical Dirichlet space of analytic functions on the open unit disc whose derivative is square area integrable. For a set E subset of partial derivative D we write D-E = {f is an element of D : lim(r -> ... -
Helices in the n-dimensional Minkowski spacetime
(ELSEVIER, 2019)In this work, we find position vectors of non-null helices in the n-dimensional Minkowski spacetime. We present methods to generate helices from polynomial curves. We also present methods to generate helices from other ... -
A diagnostic assessment to middle school students' proportional reasoning
(MEHMET TEKEREK, 2019)This study investigated Turkish middle school students' proportional reasoning and provided a diagnostic assessment of their strengths and weaknesses on the ratio and proportion concepts. A proportional reasoning test with ... -
Slant Helices that Constructed from Hyperspherical Curves in the n-dimensional Euclidean Space
(INT ELECTRONIC JOURNAL GEOMETRY, 2019)In this work, we study slant helices in the n-dimensional Euclidean space. We give methods to determine the position vectors of slant helices from arclength parameterized curves that lie on the unit hypersphere. By means ... -
Sulfonamide-derived hydrazone compounds and their Pd (II) complexes: Synthesis, spectroscopic characterization, X-ray structure determination, in vitro antibacterial activity and computational studies
(ELSEVIER, 2019)A new sulfonamide-derived prophane sulfonyl hydrazone compounds: 2-hydroxy- acetophenonepro-phanesulfonylhydrazone (afpsh), 5-Cl-2-hydroxyacetophenoneprophane sulfonylhydrazone (5-Clafpsh), 3,5-di-tert-butyl-2-hydroxyben ... -
A Variation on Absolute Weighted Mean Summability Factors of Fourier Series and its Conjugate Series
(SOC PARANAENSE MATEMATICA, 2020)In this paper, theorems concerning vertical bar(N) over bar, p(n), theta(n)vertical bar(k) factors of Fourier series and its conjugate series are studied. The presented results are generalizations two theorems of Mazhar ... -
Some basic properties of solvable Leibniz algebras
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2019)In this paper, we commence the systematic study of the structure of solvable Leibniz algebras and we give some basic properties on solvable non-Lie Leibniz algebras. Our main aim is to show a close relationship between ...
