Heegaard分裂的稳定函数和一般稳定化

Stable functions and common stabilizations of Heegaard splittings

Jesse Johnson

摘要:

本文给出了Reidemeister和Singer定理的一个新的证明:同一个三维流形的任意两个Heegaard分裂有一个公共的稳定性。证明导致一个共同的稳定的负斜率拐点和类型2尖点的Rubinstein-Scharlemann图形的两个分裂的数量方面的最小亏格的上界。

英文摘要:

We present a new proof of Reidemeister and Singer's Theorem that any two Heegaard splittings of the same 3-manifold have a common stabilization. The proof leads to an upper bound on the minimal genus of a common stabilization in terms of the number of negative slope inflection points and type-two cusps in a Rubinstein-Scharlemann graphic for the two splittings.
