On Faber-Schauder coefficients of continuous functions and divergence of greedy algorithm
收藏 引用
RUSSIAN MATHEMATICS 2019年 第5期63卷 57-62页
作者: Sargsyan, A. A. Russian Armenian Univ 123 Hovsep Emin Str Yerevan 0051 Armenia
We consider relationship between the rate of convergence to zero of the Faber-Schauder coefficients of continuous functions and the behavior of the greedy algorithm. We construct a continuous function f with Faber-Sch... 详细信息
