We give a lower bound on the boundary injectivity radius of the Margulis tubes with smooth boundary constructed by Buser, Colbois, and Dodziuk. This estimate depends on the dimension and a curvature bound only.

关于Buser–Colbois–Dodziuk-Margulis管的边界注入半径

我们给出了由Buser，Colbois和Dodziuk构造的具有平滑边界的Margulis管的边界注入半径的下界。此估计仅取决于尺寸和曲率边界。
