Youngju Kim, Tubular Neighborhoods in Complex Hyperbolic Manifolds
B236-1 IBS, Korea, Republic ofSpeaker Youngju Kim Konkuk University The collar lemma says that a closed geodesic in a real hyperbolic 2-manifold has an embedded tubular neighborhood whose width only depends on the length of the geodesic. The width of the collar does not depend on the underlying hyperbolic 2-manifold. On the other hand, a totally geodesic …
