Hyperbolic Geometry and 3-Manifold Topology
... If instead, |∂M | < ∞, prove the above result where C is a relative core. Remark 1.14. A consequence of the above exercise is that if E is an end of M , then E is homeomorphic to the unique end of a 1-ended submanifold ME of M . We will often abuse notation by referring to an end of a 3-manifold wit ...
