Suhyoung Choi

摘要:

一个实射影轨道有一个径向端点,如果端点的邻域由射影测地线划分,并发展成终止于一个公共点的测地线。它有一个全测地的结束,如果结束可以完成有全测地的边界。本文的目的是公布一些部分结果。实射影结构有时允许实射影结构的参数变形。本文证明了具有径向或全测地端点的Orbifold $\mathcal{O}$上的凸实射影结构的变形空间与\[ Hom(π_{1}(\mathcal{O}), PGL(n+1, \mathbb{R}))/PGL(n+1, \mathbb{R}).\]的相应子集的层的开子空间的并之间的同胚。一类具有广义容许端点的orbifold上的(严格)凸实射影结构

英文摘要:

A real projective orbifold has a radial end if a neighborhood of the end is foliated by projective geodesics that develop into geodesics ending at a common point. It has a totally geodesic end if the end can be completed to have the totally geodesic boundary. The purpose of this paper is to announce some partial results. A real projective structure sometimes admits deformations to parameters of real projective structures. We will prove a homeomorphism between the deformation space of convex real projective structures on an orbifold $\mathcal{O}$ with radial or totally geodesic ends with various conditions with the union of open subspaces of strata of the corresponding subset of \[ Hom(π_{1}(\mathcal{O}), PGL(n+1, \mathbb{R}))/PGL(n+1, \mathbb{R}).\] Lastly, we will talk about the openness and closedness of the properly (resp. strictly) convex real projective structures on a class of orbifold with generalized admissible ends.
