For example, U-space is uniformly regular and which makes it has fixed point property, U-space is uniformly non-square and thus super-reflexive, uniformly convex space and uniformly smooth space are U-spaces, and an Banach space is an U-space iff its dual space is U-space, etc. In1990s, a lot of work had been done on U-space theory, e.g., Tingfu Wang and Donghai Ji introduced the concepts of pre U-property and nearly U-property. Under the structure of Orlicz space, they made systematic investigation of these properties, and gave the criteria for an Orlicz space to have U-property.
U-空间具有一致正规结构进而具有不动点性质;U-空间是一致非方的,进而也是超自反的;一致凸空间和一致光滑空间是U-空间;Banach 空间为U-空间的充要条件是其对偶空间为U-空间,等等。20世纪90年代,国内外学者对U-空间理论做了很多工作,王廷辅,计东海等人先后引入了准U-性质与似U-性质的概念,并在Orlicz空间框架下对有关性质进行了系统研究,完整给出了Orlicz空间具有各种U-性质的判据。
