一个扭体映射类群的第一同调群

A twisted first homology group of the handlebody mapping class group

Tomohiko Ishida, Masatoshi Sato

摘要:

设$H_{g}$是属$g$的三维实体。利用$g\geq 2$的边界曲面$\partial H_{g}$的首次积分同调群中的系数,确定了$H_{g}$的映射类群的扭曲第一同调群.

英文摘要:

Let $H_{g}$ be a 3-dimensional handlebody of genus $g$. We determine the twisted first homology group of the mapping class group of $H_{g}$ with coefficients in the first integral homology group of the boundary surface $\partial H_{g}$ for $g\geq 2$.
