摘要

在本文中，我们确定了某些连通可定向封闭光滑 $five$ -manifolds 的还原悬浮空间的同调类型。作为应用，我们计算了 $M$ 的还原 $K$ 群，并证明了第三同调集 $\pi ^3(M)$ 和第四同调集 $\pi ^4(\Sigma M)$ 之间的悬浮映射是双射的。

The homotopy decomposition of the suspension of a non-simply-connected five-manifold

In this paper we determine the homotopy types of the reduced suspension space of certain connected orientable closed smooth

$five$

-manifolds. As applications, we compute the reduced

$K$

-groups of

$M$

and show that the suspension map between the third cohomotopy set

$\pi ^3(M)$

and the fourth cohomotopy set

$\pi ^4(\Sigma M)$

is a bijection.
