Abstract

A handlebody-knot is a handlebody embedded in the 3-sphere. We introduce an invariant for handlebody-knots derived from their Alexander polynomials. The value of the invariant is a vertex-weighted graph. As an application, we describe a sufficient condition for a handlebody-knot to be irreducible and a necessary condition for a link to be a constituent link of a handlebody-knot.

柄体结的亚历山大多项式的不变量

手柄本体结是嵌入在3球体中的手柄本体。我们引入了由亚历山大多项式导出的手柄体结的不变量。不变量的值是一个顶点加权图。作为一个应用，我们描述了把手结是不可约的一个充分条件和一个环节是把手结的组成环节的一个必要条件。
