定理0.1.设N是一个闭的双曲3-流形,其中包含一个半径为(log 3)/2 = .549306的嵌入双曲管。关于闭测地线则i)如果M N是同伦等价其中M是不可约3-流形,则f同伦于同胚。ii)若f,g:M-sN是同伦同胚,则f是g的同位素. iii)N上的双曲度量空间是路径连通的。
Theorem 0.1. Let N be a closed hyperbolic 3-manifold containing an embedded hyperbolic tube of radius (log 3)/2 = .549306... about a closed geodesic. Then i) Iff : M N is a homotopy equivalence where M is an irreducible 3-manifold, then f is homotopic to a homeomorphism. ii) If f, g: M -s N are homotopic homeomorphisms, then f is isotopic to g. iii) The space of hyperbolic metrics on N is path connected.
