AI总结:

本文证明给定圆盘上两个曲率受控的完备共形度量及一个拟对称映射,可构造三维反德西特空间中的全局双曲凸子集,使其未来、过去诱导度量与粘合映射均实现预定数据。

摘要:

设 $h^{+}$ 和 $h^{-}$ 是圆盘 $\mathbb{D}$ 上的两个完备共形度量。此外,假定度量 $h^{+}$ 和 $h^{-}$ 的共形因子的各阶导数相对于双曲度量都是有界的,并且对于某个 $\varepsilon>0$,这些度量的曲率位于区间 $\left(-\frac{1}{\varepsilon},-1-\varepsilon\right)$ 内。设 $f$ 是一个拟对称映射。我们证明了三维反德西特空间中存在一个全局双曲凸子集 $\Omega$(见定义 4.1),使得 $\Omega$ 在其未来边界上以 $h^{+}$(分别地,在其过去边界上以 $h^{-}$)为诱导度量,并且其粘合映射 $\Phi_\Omega$(见定义 5.7)等于 $f$。

英文摘要:

Let $h^{+}$ and $h^{-}$ be two complete, conformal metrics on the disc $\mathbb{D}$. Assume moreover that the derivatives of the conformal factors of the metrics $h^{+}$ and $h^{-}$ are bounded at any order with respect to the hyperbolic metric, and that the metrics have curvatures in the interval $\left(-\frac{1}ε, -1 - ε\right)$, for some $ε> 0$. Let $f$ be a quasi-symmetric map. We show the existence of a globally hyperbolic convex subset $Ω$ (see Definition 4.1) of the three-dimensional anti-de Sitter space, such that $Ω$ has $h^{+}$ (respectively $h^{-}$) as the induced metric on its future boundary (respectively on its past boundary) and has a gluing map $Φ_Ω$ (see Definition 5.7) equal to $f$.
