Abstract

A Divide with cusps is the image of a proper generic immersion from finite intervals and circles into a 22-disk which allows to have cusps. A divide with cusps is the generalization of the notion of the divide which is introduced by A'Campo. From a divide with cusps, we can define the associated link in S3S^3. In this paper, we give the characterization of the link in S3S^3 which can be described as the associated link of a divide with cusps. In particular, we prove that every strongly invertible link and 22-periodic link can be described as the link of a divide with cusps.
