B_β空间中加权K-泛函与加权光滑模的等价性

Equivalence Relation Between the Weighted K-functional and the Weighted Smoothness Moduli in B_βSpaces

研究了Bα空间上的加权K泛函与加权光滑模之间的等价性,为Bα空间上建立线性算子的加权逼近提供了有力的工具.

This paper mainly studies the equivalence relation between the weighted K functional and the weighted smoothness moduli by means of construction in B α spaces It provides a strong tool to set up the weighted approximation of linear operator in B α spaces
