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. -
ABSTRACT KOROVKIN TYPE THEOREMS ON MODULAR SPACES BY A-SUMMABILITY
(INST MATHEMATICS, AS CR, 2018)Our aim is to change classical test functions of Korovkin theorem on modular spaces by using A-summability. -
An algorithm for solving initial value problems using laplace adomian decomposition method
(2009)In this paper, we present a symbolic algorithm for solving a class of nth order linear or nonlinear ordinary differential equations with initial conditions. This algorithm is based on Laplace Adomian Decomposition Method ... -
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 ... -
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 ... -
An Application of Quasi-Monotone Sequences to Absolute Matrix Summability
(UNIV NIS, FAC SCI MATH, 2018)Recently, Bor [5] has obtained two main theorems dealing with vertical bar(N) over bar, p(n)vertical bar(k) summability factors of infinite series and Fourier series. In the present paper, we have generalized these theorems ... -
An Approach of Adaptive Network Based Fuzzy Inference System to Risk Classification in Life Insurance
(SPRINGER-VERLAG BERLIN, 2011)In this paper, we propose ANFIS based system modeling for classifying risks in life insurance. We differentiate policyholders on the basis of their cardiovascular risk characteristics and estimate risk loading ratio to ... -
Approximation by positive linear operators in modular spaces by power series method
(SPRINGER, 2017)In the present paper, we study the problem of approximation to a function by means of positive linear operators in modular spaces in the sense of power series method. Indeed, in order to get stronger results than the ... -
Approximation to Derivatives of Functions by Linear Operators Acting on Weighted Spaces by Power Series Method
(SPRINGER INTERNATIONAL PUBLISHING AG, 2016)In this chapter, using power series method we study some Korovkin type approximation theorems which deal with the problem of approximating a function by means of a sequence of linear operators acting on weighted spaces. -
The Arzela-Ascoli theorem by means of ideal convergence
(WALTER DE GRUYTER GMBH, 2018)In this paper, using the concept of ideal convergence, which extends the idea of ordinary convergence and statistical convergence, we are concerned with the I-uniform convergence and the I-pointwise convergence of sequences ... -
AN ASPECT OF LOCAL PROPERTY OF FOURIER SERIES
(YARMOUK UNIV, DEANSHIP RESEARCH & GRADUATE STUDIES, 2017)In this paper, a general theorem concerning vertical bar(N) over bar, p(n), theta(n)vertical bar(k) summability factors of Fourier series is obtained. Using this result we study a localization problem for Fourier series. -
Asymptotic formulas for eigenfunctions of the Sturm-Liouville problems with eigenvalue parameter in the boundary conditions
(ACADEMIC PUBLICATION COUNCIL, 2012)In this study, discontinuous Sturm-Liouville problems with eigenvalue parameter in the boundary conditions and with transmission conditions at the point of discontinuity are considered. We construct some basic solutions, ... -
A bound on the spectral radius of a weighted graph
(2009)Let G be simple, connected weighted graphs, where the edge weights are positive definite matrices. In this paper, we will give an upper bound on the spectral radius of the adjacency matrix for a graph G and characterize ... -
Bounded Engel elements in groups satisfying an identity
(SPRINGER BASEL AG, 2018)We prove that a residually finite group G satisfying an identity and generated by a commutator closed set X of bounded left Engel elements is locally nilpotent. We also extend such a result to locally graded groups, provided ... -
