The IRL “FuMa” for Fundamental Mathematics is a joint CNRS – Australian National University (ANU) initiative in the field of basic and applied mathematics, managed by Prof. Filipo Santambrogio (CNRS) and Stephen Roberts (ANU).

Mission and research themes

This project aims at promoting cooperation between mathematicians from every French university, and mathematicians from the Mathematical Science Institute (Australian National University) in Canberra.

The scientific area that we address is very broad, and has been recently extended (the previous version of this project was called AnGe (“ANalysis and GEometry”) in order to include all mathematical sciences with a priority for fundamental mathematics, but allowing projects on applied mathematics to emerge.

The researchers involved in the project have worked so far on various topics, including, in the latest years,

– differential geometry and topology

– representation theory

– harmonic analysis

– partial differential equations and optimal transport

– biostatistics

Support opportunities

The project is endowed with funds from CNRS and ANU, which are used to support research stays of French mathematicians in Canberra or of mathematicians from ANU in France. Longer stays (3 to 6 months) are preferred but one-month visits are also possible. Applications are done by sending a proposal, with a joint research project and a plan for the visit, to the colleagues in charge of the project (see below). The same colleagues should also be contacted for all practical details about the financial support (reimbursement, bookings, eligible expenses, amount…), which usually covers flight tickets, accommodation, and a small per-diem for local expenses. For French “enseignant-chercheurs” wishing to organize a 6 months visit to ANU the project can also support a request for a CNRS “délégation”.

laboratories involved


All labs in mathematics throughout France can take part in this project, but the project itself is hosted by UMR5208 Institut Camille Jordan, which also handles the financial matters The head of the project from the French side, to be contacted for any question is

French-Vietnamese International Emerging Action in Mathematics

Dr. Tuan Ngo Dac

Dr. Duy Tan Nguyen



The IEA ArGex (International Emerging Action Arithmetic and Galois extensions of function fields), managed by Dr. Tuan Ngo Dac (CNRS, Institut Camille Jordan, Université Claude Bernard Lyon 1) in collaboration with Dr. Nguyen Duy Tan (Institute of Mathematics, Vietnam Academy of Science and Technology) will be effective in 2020 and 2021.

Missions and research themes

This project concerns investigations in Number Theory. This is one of the fundamental branches of mathematics which has practical applications in computer science (e.g., in coding theory) and cryptography. The investigators propose several projects in arithmetic geometry and number theory that explore deep links between the analytic, arithmetic and combinatorial information encoded in certain objects associated to global function fields and their Galois extensions. Of particular interest, we focus on explicit construction of Galois extensions of function fields and on quantities attached to Anderson-Drinfeld motives, especially special zeta and L-values. We should mention that our proposal is suitable for numerical experiments as well as applications to cryptography or coding theory such as the construction of curves having many rational points. 
Keywords. Curves over a finite field, Drinfeld modules, Anderson motives, Galois cohomology, function field, Massey products, zeta and L-values, transcendence theory.

Main projects of research

Our proposal is composed of two main projects of research. The first one investigates several explicit construction of Galois extensions of function fields. The second one concerns function field arithmetic via combinatorial and transcendence methods.
