Korovkin subsets in the sense of summation process
(Tsing Hua University, 2018)In this paper we introduce Korovkin subsets for a positive linear operator T in the sense of summation process. The characterization of Korovkin subsets of C 0 (X), closure of the set of all functions with compact support ... -
Some results for max-product operators via power series method
(Univerzita Komenskeho, 2018)In this paper, we obtain an approximation theorem by max-product operators with the use of power series method which is more effective than ordinary convergence and includes both Abel and Borel methods. We also estimate ... -
Absolute Matrix Summability Factors of Fourier Series with Quasi-f-Power Increasing Sequences
(Elsevier B.V., 2018)In this paper, we have generalized a main theorem dealing with quasi-f-power increasing sequence to |A,?n|k summability method by using Fourier series. © 2018 Elsevier B.V. -
Localization property on absolute matrix summability factors of Fourier series

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 ... -
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 ... -
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 ... -
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 ... -
A symbolic algorithm for exact power series solutions of nth order linear homogeneous differential equations with polynomial coefficients near an ordinary point
