本文证明了S3中纽结的本原/Seifert-bered性质。如果满足,该属性确保结具有Dehn手术,产生小的Seifert空间(即,基础S 2和三个或更少的临界Bers)。接下来,我们描述扭曲环面结,这提供了大量的原始/塞弗特结的例子。通过分析扭曲的环面结,我们证明了几乎所有可能的三倍的多重性的临界BER出现通过原始/Seifert-bered结Dehn手术。
In this paper, we dene the primitive/Seifert-bered property for a knot in S 3 . If satised, the property ensures that the knot has a Dehn surgery that yields a small Seifert-bered space (i.e. base S 2 and three or fewer critical bers). Next we describe the twisted torus knots, which provide an abundance of examples of primitive/Seifert-bered knots. By analyzing the twisted torus knots, we prove that nearly all possible triples of multiplicities of the critical bers arise via Dehn surgery on primitive/Seifert-bered knots.
