This is to announce the Poisson 2026 Summer School and Workshop, which will be held in August in Belgium:

• Poisson 2026 Summer School: 3-7 August 2026, Antwerp, further information on https://www.uantwerpen.be/nl/personeel/sonja-hohloch/private-webpage/conference-workshop/poissonschool2026/
• Poisson 2026 Conference: 10-14 August 2026, Leuven, further information on https://wis.kuleuven.be/events/2026_poisson/poisson2026

This is the 14th in a series of international meetings on Poisson geometry aiming at bringing together researchers interested in Poisson geometry in a broad sense from all over the world.

This is the announcement of the conference “One-Dimensional Dynamics and High-Dimensional Networks” that will be held at the Centro di Ricerca Matematica Ennio De Giorgi, Pisa (Italy), on April 20-24, 2026.

The meeting will bring together researchers in dynamical systems, with an emphasis on fostering interdisciplinary exchange between experts in one- and low-dimensional dynamics and those working on high-dimensional networked systems. The conference aims to explore recent advances at the established intersection between these areas and to uncover new connections. The conference is also an opportunity to celebrate the 70th birthday of Professor Sebastian van Strien, in recognition of his many contributions to these fields.

This is to announce the opening of the registrations for the Simons Semester “Continued Fractions, Fractals, Ergodic theory and Dynamics”, which will be held at IMPAN (Poland) on 27 April - 31 May, 2026. The event was announced here.

Following up on our previous post, we are happy to announce that the Sixth DAI Day, taking place on December 19, 2025 in Padova, now has a web page and the full program is ready.

The scientific program will begin at 9:30am to end at 3:15pm. Afterwards, there will be the official assembly of the UMI Group DinAmicI from 3:30pm until 4:30pm.

If you are interested in joining the meeting, please reach out to one of the organizers: Olga Bernardi, Claudio Bonanno, Simone Paleari

This is the announcement of the conference “Dynamics, Number theory and Probability” that will be held at the University of Exeter (UK), from February 11 to 12th, 2026.

The conference is a two day event showing new directions combining ergodic theory and dynamical systems with number theory and probability theory. In order to make the talks more accessible for younger researchers (in particular last year undergraduate students and PhD students) there will be some introductory talks before the start of the conference.

This is the announcement of the two related conferences “Stability of Hamiltonian systems and beyond” and “FassòFest" that will be held at the Department of Mathematics “Tullio Levi-Civita” of the University of Padova (Italy), from January 26 to 31st, 2026.

The two conferences will focus on the most important theoretical aspects in the study of Hamiltonian systems and their stability properties, specifically motivated by the quest for extending this analysis and the available tools beyond the current range of applicability, including to certain types of non Hamiltonian systems. The conference FassòFest will be a celebration of our colleague and friend Francesco Fassò on the occasion of his 70th birthday.

The 2026 General Meeting of European Women in Mathematics will take place from 31 August to 4 September 2026 at the University of Warwick (UK). Save the date!

In addition to colloquium-style plenary talks and other activities, the programme will also include parallel sessions of more specialized minisymposia. This announcement is also a call for mini-symposia. Minisymposia should consist of six talks of twenty minutes each. To propose a minisymposium, send a brief (1-2 pages) pdf with a brief discussion of the area, and your proposed speakers to EWM2026GeneralMeeting@europeanwomeninmaths.org. A majority of your speakers and organisers should identify as women.

We are happy to announce that the Sixth DAI Day will take place on December 19, 2025 in Padova.

As is tradition by now, there will be seminars and the official assembly of the UMI Group DinAmicI.

The scientific program will begin at 9:30am and end at 3:30pm, approximately. The speakers will be Stefano Baranzini (Università di Torino), Maura Brunetti (Université de Genève), Roberto Castorrini (Università della Tuscia), and Alessandra Nardi (Università degli Studi di Padova).

As a follow up to the first announcement, it’s a pleasure to communicate that the registrations for the CIME summer school on “New Challenges in Celestial Mechanics” which will take place on June 6-10, 2026 at Hotel San Michele, Cetraro (Italy), are now open with deadline on April 15th, 2026.

The school will consist of four mini-courses: Alain Albouy, “The changes of time in classical and celestial mechanics, from the examples”; Kostantin Batygin, “Orbital Dynamics of the Trans-Neptunian Solar System”; Alessandra Celletti, “Perturbative methods in Celestial Mechanics”; Marian Gidea, “Arnold Diffusion in Celestial Mechanics”.

This is the first announcement for the five week Simons semester “Continued Fractions, Fractals, Ergodic Theory and Dynamics”, which will take place from April 27 to May 31, 2026 at the Institute of Mathematics of the Polish Academy of Sciences (IM PAN), Poland.

This semester will feature a school and a workshop:

• April 27 to May 1, 2026: Continued fractions everywhere

• May 18 to 22, 2026: Ergodic theory, fractal geometry and Diophantine approximation
