Abstract

K. Ichihara and E. Matsudo introduced the notions of Z\mathbb{Z}-colorable links and the minimal coloring number for Z\mathbb{Z}-colorable links, which is one of invariants for links. They proved that the lower bound of minimal coloring number of a non-splittable Z\mathbb{Z}-colorable link is 4. In this paper, we show the minimal coloring number of any non-splittable Z\mathbb{Z}-colorable link is exactly 4.
