证明了一类新的稳定化结果,即具有一个边界分量的可定向曲面的映射类群的同调的“次同调稳定性”。这些结果是通过构造CW近似这些群体的分类空间,在范畴的代数,其中没有细胞低于一定的消失线。
We prove a new kind of stabilisation result, “secondary homological stability,” for the homology of mapping class groups of orientable surfaces with one boundary component. These results are obtained by constructing CW approximations to the classifying spaces of these groups, in the category of-algebras, which have no-cells below a certain vanishing line.
