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 ... -
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 ... -
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 ... -
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 ...
