摘要

Given a periodic splitting sequence of a measured train track, an Agol cycle is the part that constitutes a period up to the action of a pseudo-Anosov map and the rescaling by its dilatation. We consider a family of pseudo-Anosov maps on the 2-punctured torus and on the 5-punctured sphere and describe their Agol cycles explicitly. As an application, we classify conjugacy classes of pseudo-Anosov maps in the family.
