Fields-CNAM Nonlinear Days 2025: Structures and Processes: Dynamical, Geometric, and Random
The Fields Institute, Room 309, Stewart Library, Toronto CANADA
August 18 - 22, 2025

In the last four to five decades, classical geometric function theory has evolved to encompass dynamical, metric, and probabilistic aspects. One of the notable advancements in these fields is Schramm's introduction of Schramm-Loewner Evolutions (SLE’s), which have been influential in understanding the relationship between conformally invariant and probabilistic structures. 

This workshop aims to unite researchers working in these areas and related fields, fostering collaboration and exchange of ideas for the mutual benefit of all. Equally important is the goal of nurturing the next generation of researchers. In addition to inviting emerging scholars as speakers, we will actively promote the workshop to attract participation from graduate students and post-doctoral fellows, with a focus on enhancing diversity among participants.

Ilia Binder - University of Toronto

DKO Workshop and Summer School on Transcendental Thurston Theory
University of Manchester, United Kingdom
August 26 - 29, 2025

2025 DKO Workshop and Summer School on Transcendental Thurston Theory*, will take place at the University of Manchester from August 26-29, 2025.  The workshop is intended to bring together researchers into Thurston theory and those from transcendental dynamics, as well as PhD students in holomorphic dynamics. There will be a series of introductory talks to introduce and motivate the central conjectures of Transcendental Thurston Theory, as well as research talks describing the current state of the art. The workshop is kindly funded by the Dame Kathleen Olleranshaw Trust at the University of Manchester.

2026 International Congress of Mathematicians
Pennsylvania Convention Center Philadelphia, PA
July 23 - 30, 2026

International Congress of Mathematicians (ICM) 2026 in Philadelphia, USA | 23–30 July 2026

The International Congress of Mathematicians will be held July 23-30, 2026 in Philadelphia, Pennsylvania. The congress coincides with the 250th anniversary of the signing of the Declaration of Independence and the 40th anniversary of when the last ICM was held in the U.S. The ICM offers a rare opportunity to meet some of the world's leading mathematicians and be inspired by the vast diversity of today’s mathematics.

Philadelphia provides the ICM with an excellent conference center conveniently located in the heart of the city. There is an abundance of food within walking distance, along with top quality hotels close to the conference center.

The city offers fascinating history, world class art and culture for your enjoyment, and we look forward to seeing many of you in Philadelphia!
