Teichmüller空间和带钉的层空间

Teichmüller and lamination spaces with pinnings

Tsukasa Ishibashi

摘要:

本文利用Pinnings的附加数据,将Goncharov-Shen [GS 19]引入的模空间$\mathcal{P}_{PGL_2,Σ}$的正点空间和热带点空间分别描述为Teichmüller空间和层空间.在曲面$Σ$无穿刺的情况下,我们得到了Teichmüller空间上各种函数与穿刺的关系公式:$λ$ -长度,交比坐标和Wilson线.本文用$\mathcal{P}$ -分层给出了热带化融合图的拓扑描述。基于对这些“$\mathcal{P}$型”空间的拓扑研究,我们研究了[FG 06,FG 07,MSW 13,GS 15]构造的Fock-Goncharov对偶映射$\mathbb{I}_\mathcal{A}$,$\mathbb{I}_\mathcal{X}$在扩展系综映射下的相容性.我们还讨论了手镯基地的融合。

英文摘要:

We describe the spaces of the positive and tropical points of the moduli space $\mathcal{P}_{PGL_2,Σ}$ introduced by Goncharov--Shen [GS19] as certain Teichmüller and lamination spaces, respectively, with additional data of pinnings. In the case where the surface $Σ$ has no punctures, we obtain the formulae relating various functions on the Teichmüller space with pinnings: $λ$-lengths, cross ratio coordinates, and Wilson lines. A topological description of the tropicalized amalgamation map is given in terms of $\mathcal{P}$-laminations. Based on our topological study of these "$\mathcal{P}$-type" spaces, we investigate the compatibility of the Fock--Goncharov duality maps $\mathbb{I}_\mathcal{A}$, $\mathbb{I}_\mathcal{X}$ constructed by [FG06,FG07,MSW13,GS15] under the extended ensemble map. We also discuss the amalgamation of bracelet bases.
