On the Divergence of N(?)rlund Logarithmic Means of Walsh-Fourier Series
收藏 引用
Acta Mathematica Sinica,English Series 2009年 第6期25卷 903-916页
作者: gyrgy gat Ushangi GOGINAVA Institute of Mathematics and Computer Science College of Nyíregyháza Department of Mechanics and Mathematics Tbilisi State University
It is well known in the literature that the logarithmic means 1/logn ^n-1∑k=1 Sk(f)/k of Walsh or trigonometric Fourier series converge a.e. to the function for each integrable function on the unit interval. This i... 详细信息
