The 17th International Conference on Free Boundary Problems: Theory and Applications 2026 (FBP 2026) will take place in Berlin from September 7 to September 11, 2026. The FBP conference is a flagship event that brings together the free boundary/partial differential equation community and is organized every few years with the most recent preceding conferences in the City of João Pessoa (Brazil, 2024), online in Berlin (Germany, 2021), Shanghai (China, 2017), Cambridge (UK, 2014) and Chiemsee (Germany, 2012) after the historical beginnings of the conference series in Montecatini (Italy, 1981).
FBP 2026 is a much anticipated follow-up of FBP 2021 which, due to restrictions during the Covid-pandemic at that time, was hosted online by the Weierstrass Institute for Applied Analysis and Stochastics (WIAS) Berlin. The 2026 edition of FBP will take place on-site at the Humboldt-Universität zu Berlin, Germany.
Thematically, the conference will cover a broad range of topics from modeling, analysis, optimization to numerical realization. These include aspects such as uncertainties or stochastics, data-driven intelligent numerical solution techniques (e.g. utilizing techniques of machine learning), and applications.

The scientific program of FBP 2026 will feature
The FBP 2026 scientific program consists primarily of mini-symposia. Those wishing to organize a mini-symposium should contact us at info@fbp2026.de. Please note that all talks in contributed mini-symposia will undergo a review process.
Organized mini-symposia will be scheduled in groups of four talks. The minimum number of talks in a session is thus four. You may also compose your mini-symposium of a multiple of four talks.
Please note that mini-symposium organizers are usually expected to participate in the conference, and will be assigned as session chairs during the conference.
Deadline for submission of minisymposium proposals: April 30, 2026
Notification of acceptance for mini symposia: May 04, 2026
Submit your contributed talk via the submission website. Every speaker needs to register for the conference
Please note: The conference intends to limit the number of talks per participant to one. In case a participant intends to give another talk, the corresponding sessions chair(s) and the head of the program committee (info@fbp2026.de) should be notified immediately and an argument for the differences in scopes of the talks should be provided. A decision on the request will typically be communicated within one week.
If you have been invited to contribute a talk in one of the mini-symposium of the conference, please use the submission link given to you by the mini-symposium organizers.
Deadline for submission of contributed talks: June 15, 2026
Notification of acceptance for contributed talks: June 30, 2026
The registration will start in the beginning of May.
Information on the registration fee and payment will follow soon.
End of registration: July 14, 2026
