On the Absolute Matrix Summability Factors of Fourier Series
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2018)In this paper, two known theorems on |NI", p (n) | (k) summability methods of Fourier series have been generalized for |A, p (n) | (k) summability factors of Fourier series by using different matrix transformations. New ... -
SOME RESULTS FOR MAX-PRODUCT OPERATORS VIA POWER SERIES METHOD
(COMENIUS UNIV, 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 ... -
MODULES THAT HAVE A WEAK RAD-SUPPLEMENT IN EVERY EXTENSION
(EDITURA BIBLIOTHECA-BIBLIOTHECA PUBL HOUSE, 2018)As a proper generalization of the modules with the properties (E) and (EE) that were introduced by Zoschinger in terms of supplements, we say that a module M has the property (WRE) (respectively, (WREE)) if M has a weak ... -

(MINISTRY COMMUNICATIONS & HIGH TECHNOLOGIES REPUBLIC AZERBAIJAN, 2018)In this paper, we study the boundedness of the dual Riesz transform R* and their commutators [b, R*] on generalized Morrey spaces M-p,phi(alpha,V) associated with Schrodinger operator and vanishing generalized Morrey spaces ... -
On Weak Symmetric Property of Rings
(SOUTHEAST ASIAN MATHEMATICAL SOC-SEAMS, 2018)A concept of a weak symmetric ring is defined by Ouyang and Chen, that is, a ring R is called weak symmetric if abc being nilpotent implies that acb is nilpotent for all a, b, c is an element of R. In this note we continue ... -
