SUMMARY:Youngju Kim\, Tubular Neighborhoods in Complex Hyperbolic Manifolds
DESCRIPTION:    Speaker\n\n\nYoungju Kim\nKonkuk University\n\n\n\n\n\n\nThe 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 surface with codimension bigger than 1 in a hyperbolic manifold of can be arbitrary closed to itself. Here\, we prove that an embedded complex totally geodesic surface in a complex hyperbolic 2-manifold has a tubular neighborhood whose size depends only on its area. This is a joint work with A. Basmajian.
