AI总结:

本文提出基于非相交简单环族的新对数 canonical 坐标系统,结合复化剪切型与长度/扭转型坐标,特别在m=3g-3时与芬切尔-尼尔斯顿坐标密切相关。

摘要:

我们构建了SL(2,C)紧黎曼面特征空间上的新对数 canonical 坐标系。这些坐标由1≤m≤3g-3的非相交简单环族标记,并通过结合复化剪切型与长度/扭转型坐标获得。当m=3g-3时,这些环定义了黎曼面的三叶分解,我们的坐标与复化芬切尔-尼尔斯顿坐标密切相关。

英文摘要:

We construct new sets of log-canonical coordinates on the $SL(2, \mathbb{C})$ character variety of compact Riemann surfaces. These are labelled by families of $1\leq m\leq 3g-3$ non-intersecting simple loops on the Riemann surface and are obtained by combining complexified shear-type with length/twist-type coordinates. In the case $m=3g-3$ the loops define a trinion decomposition of the Riemann surface, and our coordinates are closely related to the (complexified) Fenchel-Nielsen ones.
