Let $P: {\mathbb C} \to {\mathbb C}$ be a polynomial map with disconnected filled Julia set $K_P$ and let $z_0$ be a repelling or parabolic periodic point of $P$. We show that if the connected component of $K_P$ containing $z_0$ is non-degenerate, th

Cyclic permutations: Degrees and combinatorial types

Autor: Saeed Zakeri

Publikováno v: Journal of Combinatorial Theory, Series A. 184:105518

This note will give an enumeration of n-cycles in the symmetric group S n by their degree (also known as their cyclic descent number) and studies similar counting problems for the conjugacy classes of n-cycles under the action of the rotation subgrou

On combinatorial types of periodic orbits of the map x↦kx (mod Z)

Autor: Saeed Zakeri, Carsten Lunde Petersen

Publikováno v: Advances in Mathematics. 361:106953

We study the combinatorial types of periodic orbits of the standard covering endomorphisms m k ( x ) = k x ( mod Z ) of the circle for integers k ≥ 2 and the frequency with which they occur. For any q-cycle σ in the permutation group S q , we give

Rotation Sets and Complex Dynamics

Autor: Saeed Zakeri

This monograph examines rotation sets under the multiplication by d (mod 1) map and their relation to degree d polynomial maps of the complex plane. These sets are higher-degree analogs of the corresponding sets under the angle-doubling map of the ci
