OU Dynamical Systems seminar

The Dynamical Systems group at the Open University is organising an online seminar series.  

Our group's interests include -but are not restricted to:  Aperiodic Order,  Computer-assisted proofs in dynamical systems,  Energy systems modelling,  Holomorphic Dynamics,  Hyperbolic Geometry and Cocycle Dynamics,  Renormalisation in dynamical systems and its applications,  Symbolic Dynamics,  Tiling Dynamical Systems,  and Topological Dynamics.

Upcoming seminars

• Wednesday 11 February 2.00pm  (online)

Speaker: Alan Sola, Stockholm University

Title:  Dynamics of rational inner skew-products: the case of Möbius fiber maps

Abstract: We study a particular class of rational functions on the unit bidisk, called rational inner functions of bidegree (n,1), and the iteration theory on the 2-torus of skew-products of such maps.

In the simple case discussed in this talk each fiber map is trivial or an easily understood Möbius transformation, but the global dynamics on T^2 exhibits some complexity, encoded in the zeros of certain one-variable polynomials.

Joint work with R. Tully-Doyle (Cal Poly).
