Description: Formal Mathematics, the program to formalize, check, and manage mathematical knowledge, statements and proofs with computer support, is about to reach a critical threshold where it can efficiently support mathematical research and teaching. It has the chance to profoundly change practices in pure mathematics, as computer algebra systems have already changed computational and experimental mathematics.
Computer-checked formalizations of mathematical theories can be seen as the kind of complete presentations that Euclid or Bourbaki were aiming for. Formalized results are absolutely correct (modulo remote chances of computer failures) and can be verified by simple ``mechanical'' methods independent of high-level mathematical intuitions, abilities or traditions. They constitute a solid canon of results on which further work can be founded.
An Isabelle Proof of Cantor's Theorem
Most observers agree that methods and tools of Formal Mathematics will eventually enter ordinary mathematical practice on a broad scale. When and how this will happen is an open question that the trimester aims to help solve. Currently proofs accepted by proof assistants appear much like computer code; the discrepancy between formal and normal proofs has so far been a main obstacle against the wider adoption of Formal Mathematics.
The goal of this program is to bring together experts of Formal Mathematics, exploit their interactions, foster future collaborations, and interface them better with the mathematical mainstream. At the same time the goal is to provide a platform for junior researchers to enter Formal Mathematics. A central, unifying theme is to break down adoption barriers of formal methods in Mathematics.
Further Planned Activities: The trimester will organize work into regular get-togethers: e.g. weekly seminars, informal workshops, and open problem sessions.
The online application is closed. For the application to the school, please see here.

Venue: HIM lecture hall (Poppelsdorfer Allee 45, Bonn)
Organizers: Michael Kohlhase (Erlangen), Jacques Carette (Hamilton), Valeria de Paiva (Berkeley), Josef Urban (Praha)
Description: This one-week school teaches practical theorem proving in the three proof assistants with the greatest coverage of (research) Mathematics: Coq, Isabelle and Lean as well as smaller, more specialized systems. Key people from the research groups have indicated their willingness to teach (and supervise practical formalization attempts) in this school, drawing on tutorial material of the various systems. Participants of the school will be asked to work on small formalization projects which eventually could lead to contributions to formalization libraries. There will be a couple of introductory and special lectures.
The application is closed.
Trimester Program guests, who were invited and have confirmed to be at HIM during the period of this school, are eligible to attend this event.

June 17 - 21, 2024
Venue: HIM lecture hall, Poppelsdorfer Allee 45, Bonn
Organizers: Michael Kohlhase (Erlangen), Kevin Buzzard (London), Jacques Carette (Hamilton), Valeria de Paiva (Berkeley), Josef Urban (Praha)
Description: This workshop is devoted to the central theme of the Trimester: How do current and future developments of Formal Mathematics impact and assist active research in central areas of pure mathematics. Talks will focus on examples of such interactions, as well as on the development of adequate techniques. Some half-days will be reserved for informal demonstrations, collaborations and co-working.

July 8 - 12, 2024
Venue: HIM lecture hall, Poppelsdorfer Allee 45, Bonn
Organizers: Kevin Buzzard (London), Jacques Carette (Hamilton), Valeria de Paiva (Berkeley), Michael Kohlhase (Erlangen), Josef Urban (Praha)
Description: This workshop focusses on the man / machine interaction in Formal Mathematics. Presently, most formal proofs are practically unreadable by average mathematicians, as they appear like specialized computer code. Can this be improved by making proof languages "readable", or by automatic translation from formalizations into a natural language-like format?
On the other hand, can the formalization process be made as natural for mathematicians as typing texts into LaTeX, so that formalization and proof-checking happen concurrently without appreciable extra effort? Can AI-methods help with translations from informal to formal? Could (AI) translation techniques translate parts of the vast corpus of existing mathematical texts into formalizations?

July 29 - August 2, 2024
Venue: HIM lecture hall, Poppelsdorfer Allee 45, Bonn
Organizers: Kevin Buzzard (London), Jacques Carette (Hamilton), Valeria de Paiva (Berkeley), Michael Kohlhase (Erlangen), Josef Urban (Praha)
Description: This workshop will focus on the organization, modularization, and curation of mathematical libraries. Contributions/talks can address any combinations of the five aspects of the Tetrapod (see Fig. 1). Though the workshop has a primary focus on formal libraries, organizational aspects of informal mathematics (e.g. via ontologies) can be addressed, if they contribute to machine-processing of the mathematical heritage.

June 10 - 14, 2024
Venue: HIM lecture hall, Poppelsdorfer Allee 45, Bonn
Kevin Buzzard will be giving some lectures at HIM on the current state of the project to formalise Fermat's Last Theorem in Lean. The lectures will be suitable for master's students and above interested in formalisation and number theory. During the week he will suggest many formalisation topics to work on and guide the attendees through how to contribute to the project via individual or group work. Most of the time will be spent working on Lean projects. Anyone interested is welcome, including Lean beginners, although you would be better off if you've worked through some of the free online textbook "Mathematics in Lean".
We will be focussing on defining automorphic forms, stating profound theorems linking them to Galois representations, and also stating R=T theorems. We will need to formalise Masters level mathematics across number theory, geometry, analysis and algebra, and will focus on whatever the strengths of the audience are.
We will start every day formally with a lecture 11-12 in the HIM lecture hall.
