透镜空间的两个Goeritz群的亏格

Genus two Goeritz groups of lens spaces

Sangbum Cho

摘要:

给定3-流形的亏格- $g$ Heegaard分裂,Goeritz群被定义为流形的保向同胚的保向同胚的合痕类的群.本文给出了透镜空间$L(p, 1)$亏格为2的Heegaard分裂的Goeritz群,并给出了它们的显式表示.

英文摘要:

Given a genus-$g$ Heegaard splitting of a 3-manifold, the Goeritz group is defined to be the group of isotopy classes of orientation-preserving homeomorphisms of the manifold that preserve the splitting. In this work, we show that the Goeritz groups of genus-2 Heegaard splittings for lens spaces $L(p, 1)$ are finitely presented, and give explicit presentations of them.
