1截紧李群是有限群经环面的任意扩展。本文计算了$H$截断的紧李群$G$和$H$的$Map_*(BG,BH)$、$Map(BG,BH)$和$Map(EG, B_GH)^G$的同伦类型,证明了它们完全是在$G$到$H$的同态空间中计算的。这些结果推广了众所周知的当$H$是有限的情况,以及$H$由于Lashof, May和Segal而紧的阿贝尔的情况。
A 1-truncated compact Lie group is any extension of a finite group by a torus. In this note we compute the homotopy types of $Map_*(BG,BH)$, $Map(BG,BH)$, and $Map(EG, B_GH)^G$ for compact Lie groups $G$ and $H$ with $H$ 1-truncated, showing that they are computed entirely in terms of spaces of homomorphisms from $G$ to $H$. These results generalize the well-known case when $H$ is finite, and the case of $H$ compact abelian due to Lashof, May, and Segal.
