摘要
H.Mohebi与Sh.Rezapour在研究Banach空间中的逼近问题时,提出了quasi-Chebyshev子空间及ε-weakly Chebyshev子空间等概念,在文中作者就这些逼近性质在置换空间PBBs中进行了讨论.
H. Mohebi and Sh. Rezapour gave the definitions of quasi-Chebyshev subspace and e-weakly Chebyshev subspace etc when they studied the approximation properties in Banach space. In the paper the authors discuss these properties in the substitution spaces PBBs.
