摘要

摘要证明了如果K是一个非平凡的零同伦结，使得$Y-K$不存在$S^1\ * S^2$和，则K上的零点手术不存在$S^1\ * S^2$和。这推广了Hom和Lidman的结果，他们证明了Y是不可约有理同调球的情况。

Null-homotopic knots have Property R

Abstract We prove that if K is a nontrivial null-homotopic knot in a closed oriented 3–manfiold Y such that $Y-K$ does not have an $S^1\times S^2$ summand, then the zero surgery on K does not have an $S^1\times S^2$ summand. This generalises a result of Hom and Lidman, who proved the case when Y is an irreducible rational homology sphere.
