正性、交比与领圈引理
Positivity, cross-ratios and the Collar Lemma
AI总结:
本文证明带尖点或无限型曲面基本群的 $Θ$-正表示满足领圈引理且交比为正,并据此证明这类表示在表示簇中构成闭子集。
摘要:
我们证明了曲面(可能带尖点或为无限型)基本群的 $Θ$-正表示满足领圈引理,且其相关交比为正。由此我们推断,$Θ$-正表示构成表示簇的闭子集。
英文摘要:
We prove that $Θ$-positive representations of fundamental groups of surfaces (possibly cusped or of infinite type) satisfy a collar lemma, and their associated cross-ratios are positive. As a consequence we deduce that $Θ$-positive representations form closed subsets of the representation variety.
