    Rotation sets and almost periodic sequences
    (Springer, 2016-10) Jäger, T.; Passeggi, A.; Štimac, Sonja; Department of Mathematical Sciences, School of Science
    We study the rotational behaviour on minimal sets of torus homeomorphisms and show that the associated rotation sets can be any type of line segment as well as non-convex and even plane-separating continua. This shows that the restriction which hold for rotation sets on the whole torus are not valid on minimal sets. The proof uses a construction of rotational horseshoes by Kwapisz to transfer the problem to a symbolic level, where the desired rotational behaviour is implemented by means of suitable irregular Toeplitz sequences.
