我们构造了一个函子KG,它取每一对单形g -梯度范畴(D,Df)到一个无限环g空间KG(D,D')。当D'=D时,其同伦群n%KG(D,D)与D的等变k群KnRepD重合。应用包括在等变分类空间间映射BO(G} -^ BPL(G}-^> BTop(G})的等变无限展开的简单构造。
We construct a functor KG which takes each pair of monoidal G-graded categories (D,Df) to an infinite loop G-space KG(D,D'). When D'=D, its homotopy groups n%KG(D,D) coincide with the equivariant K-groups KnRepD of D. Applications include the simple construction of equivariant infinite deloopings of the maps BO(G}—^BPL(G}-^> BTop(G} between equivariant classifying spaces.
