内爆截面

摘要：

在这篇综述文章中，我们描述了内爆截面，这是为了解决的问题，哈密尔顿$K$ -空间的截面通常是不辛的。在一些具体的例子中，我们对比了一些内爆截面的交同调与它们的同调交空间。此外，我们还计算了与单连通、光滑、定向流形的开锥相关的交空间的同调，以及这种流形的悬挂。

英文摘要：

In this survey article, we describe imploded cross-sections, which were developed in order to solve the problem that the cross-section of a Hamiltonian $K$-space is usually not symplectic. In some specific examples we contrast the intersection homology of some imploded cross-sections with their homology intersection spaces. Moreover, we compute the homology of intersection spaces associated to the open cone of a simply connected, smooth, oriented manifold and the suspension of such a manifold.
