Dynamics, Rigidity and Arithmetic in Hyperbolic Geometry
ICERM, Brown University, Providence, Rhode Island
May 15 - 19, 2023

This workshop will focus on the interplay between dynamics, rigidity, and arithmetic in hyperbolic geometry and related areas. There have been many striking developments in recent years, particularly related to totally geodesic submanifolds in both finite and infinite volume hyperbolic and even complex hyperbolic manifolds.

One aim of this workshop is to expose young researchers to these breakthroughs providing them with the necessary background from dynamics, and geometry to allow them to appreciate some of these recent advances, and prepare them to make new original contributions. For this purpose, we will have minicourses on "Arithmeticity, Superrigidity and totally geodesic manifolds", and "Rigidity and geodesic planes in infinite volume hyperbolic manifolds". These courses will be preceded by an introductory minicourse on Hyperbolic geometry. We will also have a minicourse on "Understanding of geodesic planes in hyperbolic 3-manifolds via computations and visualization". In addition, we wish to bring together experts in these fields to discuss the recent developments and open problems that lie at the crossroads of these different fields and to encourage more interaction among people working in these diverse areas.

This workshop is partially funded by NSF CAREER award DMS-1651563workshop at ICERM, May 15-19, 2023,

Homogeneous Dynamics and Geometry in Higher-Rank Lie Groups
IHES -Institut des Hautes Études Scientifiques, Bures-sur-Yvette, France
June 19-23, 2023


The goal of the workshop is to explore links between homogeneous dynamics and recent developments on infinite-covolume discrete subgroups of Lie groups, including images of Anosov representations and generalizations. There will be three minicourses and a dozen research talks. 

This workshop is organized by Martin Bridgeman (Boston College), Richard Canary (University of Michigan), Fanny Kassel (CNRS & IHES), Hee Oh (Yale University), Maria Beatrice Pozzetti (Universität Heidelberg), and Jean-François Quint (CNRS & Université de Bordeaux).

Minicourses:

Northwestern RTG-Dynamics Summer School
Northwestern University, Evanston, Illinois 60208
June 20—30, 2023

Two-week summer school at Northwestern University, June 20—30, 2023. The school will feature mini-courses by Alena Erchenko, Mikolaj Fraczyk, Nicholas Miller, Amir Mohammadi, Daren Wei, and Kurt Vinhage, Planned topics for mini-courses include: effective equidistribution in unipotent dynamics, Kakutani equivalence and time change rigidity for unipotent flows, superrigidity and arithmeticity, flexibility in dynamical systems, invariant and stationary random subgroups.

The first week will include some preparatory courses as well as courses for advanced undergraduates.  (Undergraduates should have at a minimum complete a semester courses in real analysis and abstract algebra.)  

Registration: interested participants should apply for participation and funding at math programs (https://www.mathprograms.org/db/programs/1451).  Please note: our primary source of funding is limited for participants who are U.S. citizens or permanent residents.  There is limited additional funding for participants who are not citizens or permanent residents.

Facets of complex dynamics
Mathematics and Interactions in Toulouse (MINT) Toulouse, France
June 26 to June 30, 2023

Facets of Complex Dynamics

The aim of this summer school is to introduce Master and PhD students to a number of current research topics in holomorphic dynamics, ranging from one-variable to multivariable dynamics, and from iterative to continuous-time dynamics.

Speakers:

  • T-C Dinh & V-A Nguyen (National University of Singapore & Université de Lille) Theory of Currents and Applications in Dynamics and Foliation Theory (I) and (II)

  • N. Fagella (Universitat de Barcelona, CRM)"Transcendental dynamics and bifurcations"

  • T. Gauthier (Laboratoire de Mathématiques d'Orsay)"Unlikely intersection problems in arithmetic dynamics"

  • R. Roeder (IUPUI - Indianapolis) "Dynamics of holomorphic and birational group actions on complex surfaces"

  • P. Roesch (Institut de Mathématiques de Toulouse) "Julia set of rational maps, examples".

Each mini-course aims at providing an introduction to an active area of research in Complex dynamics while offering enough background to be accessible to Master students.

MINT Graduate School can provide some financial support to students wishing to attend the school. If you are planning to apply for MINT financial support, please register
at your earliest convenience - and before April, 27th - at the following address:
