论文摘要
我们表明,每个封闭的,拓扑的,拓扑的PSC 4 manifold都可以从拓扑上的PSC 4-纤维中获得0和1效率获得,其中最多与原始数量一样大。
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.
