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

Complex Geometry, Complex Analysis and Dynamics
CIRM, south of France
7 – 11 July, 2025

The Centre International de Rencontres Mathématiques (CIRM) was created in 1981 by the French mathematics community and has become an increasingly popular destination. It provides all the facilities and equipment that conference organizers and participants need, allowing for collaborative work in mathematical sciences and other disciplines. CIRM is one of the largest mathematical meeting centers in the world. At full capacity, Cirm welcomes every week about a hundred participants from all over the world. The events, of high scientific quality, cover the whole spectrum of mathematics and its interactions.

Complex Geometry, Complex Analysis and Dynamics on July 7 - 11, 2025.  For more information, please check website: https://conferences.cirm-math.fr/3351.html and also the participants' list: https://www.cirm-math.fr/Listes/liste_pre_verif.php?id_renc=3351&num_sem...

2025 Early-Career Complex Dynamics Workshop
Indiana University, Bloomington, Indiana
July 15 - 17, 2025

2025 Early-Career Complex Dynamics Workshop
July 15-17, 2025
Indiana University
Bloomington, IN

 Complex dynamics is connected to many fields: analysis, group theory, topology, geometry, … The aims of the workshop are to highlight topics of current interest, to encourage collaboration on open problems, and to foster lasting professional relationships. This year’s themes include connections with mapping class groups.
 
The goal is to have a small, informal environment where questions are welcome.

Confirmed participants include:
Jim Belk, U Glasgow
Katherine Booth, Georgia Tech/Vanderbilt
Caroline Davis, Indiana University/SUNY StonyBrook
Darragh Glynn, U Warwick
Insung Park, SUNY StonyBrook
Roberta Shapiro, University of Michigan

Zachary Smith, Northwestern University
Yvon Verberne, University of Western Ontario

 Funding, from NSF and Indiana University, is available. Applicants should send an email and cv to
organizer Kevin Pilgrim pilgrim@indiana.edu . Graduate students should also ask a faculty advisor
to send an email letter of support. Applications received by June 14, 2025 will receive priority.
