| Popis: | In this paper, we present results for the forcing relation on the set of braid types of periodic orbits of a rotational horseshoe on the annulus. Precisely, we are concerned with a family of periodic orbits, called the Boyland family, and we prove that for each pair$(r,s)$of rational numbers with$rin$(0,1)$, there exists a non-monotone orbit$B_{r,s}$in this family which has pseudo-Anosov type and rotation interval$[r,s]$. Furthermore, the forcing relation among these orbits is given by the inclusion order on their rotation sets. It is also proved that the Markov partition associated to each Boyland orbit comes from a pruning map which projects to a bimodal circle map. This family also contains the Holmes orbits$H_{p/q}$, which are the largest for the forcing order among all the$(p,q)$-orbits of the rotational horseshoe. |
