ON LOCAL PROPERTY OF VERTICAL-BAR-A-VERTICAL-BAR(K) SUMMABILITY OF FACTORED FOURIER-SERIES

[摘要] Quite recently, Bor [J. Math. Anal. Appl. 163 (1992), 220-226] proved a result on the local property of \($) over bar N, p(n) \(k) summability of factored Fourier series, which includes some known results. In this paper we extend his result to more general cases by taking normal matrices instead of weighted mean matrices. (C) 1994 Academic Press, Inc.
