三环面保亏格三Heegaard分裂的自同构

Automorphisms of the three-torus preserving a genus three Heegaard splitting

Jesse Johnson

摘要:

Heegaard分裂的映射类群是将Heegaard曲面映射到其自身上的环境流形的自同构集合中的连通分量的群。对于亏格为3的Heegaard分裂的3-torus,我们找到了一个八元生成集这个组。其中6个生成元诱导出3-环面的映射类群的生成元,其余2个生成元在3-环面中是平凡的。

英文摘要:

The mapping class group of a Heegaard splitting is the group of connected components in the set of automorphisms of the ambient manifold that map the Heegaard surface onto itself. For the genus three Heegaard splitting of the 3-torus, we find an eight element generating set for this group. Six of these generators induce generating elements of the mapping class group of the 3-torus and the remaining two are isotopy trivial in the 3-torus.
