On application of matrix summability to Fourier series [PDF]

open access: yes, 2017
WOS: 000427318700016Bor has recently obtained amain theorem dealing with absolute weighted mean summability of Fourier series. In this paper, we generalized that theorem for vertical bar A, theta(n)vertical bar k summability method.

Regular matrix methods of summability and real interpolation [PDF]

open access: yes, 2021
We show that the Banach–Saks property with respect to a regular positive matrix method of summability is inherited by the real interpolation spaces from a space forming the interpolation family and possessing this property. The proof refers to the Galvin–

On an inclusion theorem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We have established a relation between θ−|R,pn|k and θ−|R,qn|k summability methods, k>1, which generalizes a result of Sunouchi (1949) on |R,pn| and |R,qn| summability methods.

On Strong Approximation in Generalized Hölder and Zygmund Spaces

open access: yesComputer Sciences & Mathematics Forum, 2023
The strong approximation of a function is a useful tool to analyze the convergence of its Fourier series. It is based on the summability techniques. However, unlike matrix summability methods, it uses non-linear methods to derive an auxiliary sequence ...

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

A bounded consistency theorem for strong summabilities

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1989
The study of R-type summability methods is continued in this paper by showing that two such methods are identical on the bounded portion of the strong summability field associated with the methods.
