摘要
本文利用等度变差集,考虑单变量和双变量情形下变指标Banach空间值的有界Wiener变差空间和有界Riesz变差空间中准紧集的充分条件.
By equivariated sets,we consider sufficient conditions for precompact sets in variable exponent Banach spacevalued bounded Wiener variation spaces and bounded Riesz variation spaces in univariate and bivariate cases,respectively.
