DIVISION FOR STAR MAPS WITH THE BRANCHING POINT FIXED
Ll. ALSED\`A and X. YE
Abstract.
We extend the notion of division given for interval maps (see Ref. 10) to the $n$-star and study the set of periods of star maps such that all their periodic orbits with period larger than one have a division. As a consequence of this result we get some conditions characterizing the star maps with zero topological entropy.
