给定一个knotKin的三球,我们解决的问题:哪Dehn手术上K界负定四维流形?我们表明,答案取决于一个numberm(K),这是一个光滑的和谐不变量。我们研究这个不变量的性质,并计算它的环面结。
Given a knotKin the three-sphere, we address the question: Which Dehn surgeries onKbound negative-definite four-manifolds? We show that the answer depends on a numberm(K), which is a smooth concordance invariant. We study the properties of this invariant and compute it for torus knots.
