本文研究了闭3-流形M3中纽结K的薄表示,当M不具有透镜空间作为连通和项时,对一定的斜率,M通过Dehn手术产生S3,首先证明了关于M的任意脊的所有薄表示都只有局部极大值.如果M是一个透镜空间,K相对于给定的标准脊具有基本的薄表示(透镜空间M的),并且只有局部极大值,则我们证明了K是M中的0-桥或1-桥辫;此外,我们证明了K与这类脊之间的最小相交至少为3,并且最终,如果手术K的核心通过r-Dehn手术产生S3,证明了如下不等式:jrj 2 g,w是K的亏格。AMS分类57 M25; 57 N10,57 M15
This paper concerns thin presentations of knots K in closed 3-manifolds M 3 which produce S 3 by Dehn surgery, for some slope .I f Mdoes not have a lens space as a connected summand, we rst prove that all such thin presentations, with respect to any spine of M have only local maxima. If M is a lens space and K has an essential thin presentation with respect to a given standard spine (of lens space M ) with only local maxima, then we show that K is a 0-bridge or 1-bridge braid in M ; furthermore, we prove the minimal intersection between K and such spines to be at least three, and nally, if the core of the surgery K yields S 3 by r -Dehn surgery, then we prove the following inequality: jrj 2 g ,w here gis the genus of K.
