| English abstract | We study the Ashkin-Teller model on a Cayley tree of finite coordination z as a mapping problem. The stability analysis of the fixed points is used to obtain set of phase diagrams as a function of z. Our treatment reveals a rich variety of distinct topologies obtained for these diagrams |
