具有一个边界分量的可定向曲面的嵌入映射类群

Embedding mapping-class groups of orientable surfaces with one boundary component

Lluis Bacardit

摘要:

设$S_{g,1,p}$是亏格$g$的可定向曲面,具有一个边界分量和$p$穿刺.设$\mathcal{M}_{g,1,p}$是$S_{g,1,p}$相对于边界的映射类群。我们构造了同态$\mathcal{M}_{g,1,p} \to \mathcal{M}_{g',1,(b-1)}$,其中$g' \geq 0$和$b\geq 1$.证明了所构造的同态$\M_{g,1,p} \to \M_{g',1,(b-1)}$是单射的。$g = 0$的这些嵌入之一是经典的。

英文摘要:

Let $S_{g,1,p}$ be an orientable surface of genus $g$ with one boundary component and $p$ punctures. Let $\mathcal{M}_{g,1,p}$ be the mapping-class group of $S_{g,1,p}$ relative to the boundary. We construct homomorphisms $\mathcal{M}_{g,1,p} \to \mathcal{M}_{g',1,(b-1)}$, where $g' \geq 0$ and $b\geq 1$. We proof that the constructed homomorphisms $\M_{g,1,p} \to \M_{g',1,(b-1)}$ are injective. One of these embeddings for $g = 0$ is classic.
