我们证明,每个封闭的、有向的、拓扑 PSC 4 流形都可以通过拓扑 PSC 4 轨道的 0 和 1 手术获得,其中第一 Betti 数消失,第二 Betti 数最多与原始 Betti 数一样大。
We show that every closed, oriented, topologically PSC 4-manifold can be obtained via 0 and 1-surgeries from a topologically PSC 4-orbifold with vanishing first Betti number and second Betti number at most as large as the original one.
