Beyond Uniform Hyperbolicity conference
ICTP, Trieste, Italy
June 2 - June 13, 2025

We are pleased to announce the next Beyond Uniform Hyperbolicity conference June 2 - June 13, 2025, at the ICTP, Trieste, Italy. This conference belongs to the Beyond Uniform Hyperbolicity series of conferences that have been held every 2-3 years since 2001. The conference will consist of 6 mini courses (see the webpage for more details) and plenty of opportunities for informal discussions and work groups, as well as a small number of talks and a poster session. If you are interested in participating, please fill out the pre-registration form (by January 15th in case you apply for financial support). Make sure to indicate your preference on presenting a talk, and your funding request. We hope to cover the local expenses of a significant proportion of participants. However, we expect that participants who have access to other forms of support to cover part or all of their expenses.

Borderline billiards theory (such as billiards with no borders)
Cortona, Italy
June 29 - July 4, 2025

COURSE ON "DYNAMICS OF BILLIARDS"

Krzysztof Burdzy (University of Washington)

Borderline billiards theory (such as billiards with no borders)

The lecturer will discuss several models, including Archimedes' principle for an ideal gas, pinned billiard balls, rotating billiard tables, and billiard balls in a space without walls. Some techniques that are related to or arose in these areas will be presented.

Marco Lenci (Universita’ di Bologna)

An introduction to the theory of chaotic billiards

The course will give an introduction to the theory of hyperbolic billiards, developed by Sinai and his school some 50 years ago. This theory — somehow sought after since the times of Boltzmann, Poincaré and Birkhoff — has had a profound impact on the development of the theory of chaotic dynamical systems and its applications, and earned Yakov Sinai his 2014 Abel Prize. The audience will get acquainted with the basic tools of hyperbolic dynamics in the presence of singularities and will see a fairly detailed sketch of the proof of the ergodicity of the Sinai billiard, a.k.a. Lorentz gas. A minimal background in measure theory is required; some rudiments of ergodic theory are welcome  

 

Dynamics and Rigidity

Extremal Polynomials and Dynamical Systems
The Carlsberg Academy, Gamle Carlsbergve, Copenhagen
August 19-22 2025

The aim of the conference is to bring together researchers working in areas related to Approximation Theory or Dynamical Systems in a broad sense to promote interaction and exchange of ideas.  We have an exciting lineup of 10 plenary talks by international experts. Please submit your abstract if you would like to give a contributed presentation (20–30 minutes).

We expect to open the registration and submission of abstracts at the end of March.

Organizer: Carsten Lunde Petersen, Henrik L. Pedersen
