There are five minicourses around Poisson geometry and related topics:

• ​"Introduction to Poisson structures via polynomial Poisson brackets" by Jiang-Hua Lu (University of Hong Kong, China).

​Lecture 1+2, Lecture 3+4, Exercise sheet​

• ​"Integrable systems: from Poisson to Nijenhuis" by Alexey Bolsinov (Loughborough University, UK).

​Lecture 1, Lecture 2, Lecture 3, Lecture 4, ​Exercise sheet​

• ​"Hamiltonian Group Actions and Fixed Points" by Tara Holm (Cornell University, USA).

​Lecture 1, Lecture 2, Lecture 3, Lecture 4, Exercise sheet​

• ​"Symplectic connections" by Simone Gutt (ULB, Belgium).

​Lectures 1+2+3+4​

• ​"Courant algebroids and their integrations" by Miquel Cueca Ten (KU Leuven).

Lecture 1, Lecture 2, Lecture 3+4​

​At the poster session, junior participants may present their results via a poster to the other participants.

• There are 73 posters on display on poster boards during the whole week.​
• On Monday afternoon, 15 participants presented their posters via pitch talks.
• The winners of the Best Poster Award were determined by votes of all participants. The results were as follows: The First Price went to Ana Carolina Mançur (University of São Paulo) for her poster "Manin triples on multiplicative Courant algebroids". There was a draw for the Second Price, so it was awarded ex aequo to 2 participants. A Third Price was therefore not awarded. These Second Prices went to Ilias Ermeidis (Aristotle University of Thessaloniki) with poster "Deformations of normal Lie subgroups" and Antonio Maglio (Institute of Mathematics, Polish Academy of Sciences) with poster "Shifted contact higher Lie groupoids".  Every winner was in addition awardsd a math book donated by World Scientific.

• Here is the SCHEDULE (update Aug 3, 2026) of the Poisson Summer School 2026.
• Here is the BOOKLET (update Aug 3, 2026) of the Poisson Summer School 2026.
• Here you can download the Poisson 2026 poster (PDF, 13MB).

The Poisson 2026 Summer School will take place during August 3-7, 2026 "on campus only", i.e., there will not be any online/hybrid options for participation!

• WHERE:​ The Poisson Summer School 2026 takes place in the very city center of Antwerp/Belgium on the campus "stadscampus" of the University of Antwerp in the building "Meerminne", briefly "building S.M" or "building M". The lectures and exercise sessions are in auditorium S.M.001 which is the biggest lecture hall in the building and on the right hand side after entering the building through the main entrance. The poster session takes place in the very center of building M. The reception will be in building M on the right hand side between the main entrance and auditorium S.M.001.
• ATTENTION: the summer school does thus NOT take place on Campus Middelheim where the math department is located!

The REGISTRATION for the Poisson 2026 Summer School in Antwerp/Belgium is now closed. 

Registration deadlines:

• March 8th, 2026 for junior participants applying for funded accommodation.
• June 28th 2026 for all other participants.

We have a certain amount of funding at our disposal to cover housing for junior participants, in particular, to encourage participation of underrepresented groups (like, for example, female participants) and to support attendance when the financial means of the home university/country are insufficient. 

The funded accommodation is in a double room in the ASH (one of the two Antwerp youth hostels) including breakfast together with either somebody of the same gender or (when so declared mutually by 2 funded participants) with the preferred other funded participant. The funded housing covers the period between arrival on Sunday 2nd of August 2026 and departure on Saturday 8th of August 2026 --- unless the funded participant registered also for the subsequent Poisson 2026 Conference in Leuven, then departure is Sunday 9th of August 2026. 

• See HERE for travel information to Antwerp/Belgium. 
  
• For the speakers, we reserved rooms in the Leonardo Hotel right next to the Central train station. It is located HERE (Attention: there is another Leonardo Hotel in Antwerp, but about 20min by foot away from the Central Train Station! Don't confuse them!)
• The funded housing for junior participants is in the ASH (one of the two youth hostels in Antwerp). It is located HERE.​
