Jean-François Coulombel

I am a researcher in mathematics working for the CNRS, and I work at the Institut de Mathématiques de Toulouse (France). Previously I used to work at the Laboratoire Paul Painlevé in Lille and then at the Laboratoire de Mathématiques Jean Leray in Nantes.

I have coordinated the ANR research projects INTOCS and NABUCO. I have also been a participant of the ANR project BoND. I am now a participant of the ANR project HEAD.

On my webpage, you can find my resume and download my publications.

I have signed the Cost of knowledge petition and thereby stopped submitting my work to all Elsevier, Springer, Wiley and Taylor & Francis journals. For other reasons, I have also stopped submitting my work to all SIAM journals. I have also stopped writing reports for these journals (all five above editors). No need to ask me for a favor. The answer will be no. I strongly support all colleagues who sign the Cost of knowledge petition and stick to it.

I have unfortunately been unaware of these editorial issues for a long time. Some of my work has been published in Elsevier, Springer, SIAM or Wiley journals in the past. I have also written some reports for these journals. I can not rewrite the past. All I can say is that I wish I had been more aware of all these issues earlier in my career.

The Institut de Mathématiques de Toulouse is the home of the Annales de la Faculté des Sciences de Toulouse that is a completely free journal for both authors and readers. The Annales are part of the Centre Mersenne which edits free access journals and proceedings.

I strongly encourage all colleagues to submit their work for publication in the Annales de la Faculté des Sciences de Toulouse and other (so-called) diamond open access journals. A partial list of such mathematical journals may be found here, here or in the Free Journal Network. Further information (all disciplines) may be found in the Directory of Open Access Journals.

Due to climate change issues (about which I strongly recommend reading the 6th IPCC Synthesis Report), I have decided to limit my travel plans. I will no longer travel in France by plane and will also not travel by plane abroad for short stays (such as conferences). According to me, this is the minimal requirement for my individual professional behavior in order to meet the standards of the 2015 Paris agreement on climate change (and I very well know that this will be far from sufficient...).

French readers may take some time reading Allons nous continuer la recherche scientifique ? by Alexandre Grothendieck (a conference given in January 1972 at CERN in Geneva). A short extract is the following: ``Finalement, ce qui compte pour moi, ce n'est pas tellement d'atteindre la position de pureté morale qui est parfaitement impossible au sein de cette société (...), ce qui compte, c'est que nous soyons un ferment de transformation, un facteur de transformation là où nous nous trouvons.''

HEAD is a research project granted by the French Agence Nationale de la Recherche for five years (October 1st 2024 - September 30th 2029). The acronym stands for Hyperbolic Equations, Approximations & Dynamics. The project is focused on the analysis of the long-time dynamics of first-order hyperbolic systems of nonlinear partial differential equations and their approximations by numerical schemes, vanishing viscosity or in the dispersionless limit.

See more information on the HEAD project webpage.

NABUCO was a research project granted by the French Agence Nationale de la Recherche for five years (January 1st 2018 - December 31st 2022). The acronym stood for NumericAl BoUndaries and COupling. The main scientific objectives of the project dealt with numerical boundary conditions and coupling problems for hyperbolic and dispersive PDEs. The project was a continuation of some aspects of the former ANR project BoND (standing for Boundaries, Numerics, Dispersion).
