On the Approximate weak chebyshev greedy algorithm in uniformly smooth Banach spaces
收藏 引用
JOURNAL OF MATHEMATICAL ANALYSIS AND APPLICATIONS 2016年 第1期436卷 288-304页
作者: Dereventsov, A. V.
We study greedy approximation in uniformly smooth Banach spaces. The weak chebyshev greedy algorithm (WCGA), introduced and studied in [6], is defined for any Banach space X and a dictionary D, and provides nonlinear ... 详细信息

We present new results regarding Lebesgue-type inequalities for the weak chebyshev greedy algorithm (WCGA) in uniformly smooth Banach spaces. We improve earlier bounds in [19] for dictionaries satisfying a new propert... 详细信息
