The goal of this meeting is to bring together researchers in applied mathematics, especially those involved in scientific cooperation between France and Romania.

For the previous editions of the conference (organized every two years alternately in France and Romania), see: Bordeaux (2018)         Iasi (2016)        Lyon (2014)        Bucarest (2012).

The 2020 edition was initially scheduled in Brasov, Romania and was canceled at the last minute due to the Covid pandemic. Many thanks to the organizers of the 2020 edition for their great and careful work that could not bear fruit immediately, but was extremely useful to prepare the 2022 edition.

The fifteenth French-Romanian Colloquium on Applied Mathematics will be held from August 29 to September 2, 2022 at the Toulouse Institute of Mathematics located on the campus of Paul Sabatier University in Toulouse, France.

The reception is scheduled for Monday, August 29 starting from 11:45 a.m. and the presentations will begin at 2:15 p.m.

The Colloquium will end on Friday, September 2 at 12:30 p.m.

We hope that this will allow most participants from France to make the journey on Monday morning, and the return journey on Friday afternoon.

The Institute of Mathematics occupies the buildings 1R1, 1R2, and 1R3. The following rooms will be used for the colloquium :

- amphitheater Laurent Schwartz (building 1R3, ground floor)

- Katherine Johnson (building 1R3, 1st floor)

- Frances Pellos (building 1R2, 2nd floor, room 207)

- Jean Cavaillès (building 1R2, 1st floor, room 132).

The organizers are indebted to Mihai N. Pascu from Transilvania University in Brașov for creating the website.

The 15th French-Romanian colloquium in Applied Mathematics is organized at the Institute of Mathematics in Toulouse, with the support of the Institut Universitaire de France, Université Paul Sabatier, Labex CIMI, Région Occitanie, the GDR CNRS CALVA and with partial support from the Institute of Mathematics "Simion Stoilow" of the Romanian Academy, project IRN-CNRS ECO-Math.

  GDR CALVA 

Registration is free, but mandatory. To register,  please use the connection button (upper right corner of the webpage). This requires a SciencesConf account (if you participated in the previous edition of the colloque, you may use the same credentials to login, otherwise you can create an account). The registration site is open until July 15, 2022.

If you would like to make a presentation (oral/poster) in one of the minisimposia of the colloquium, please complete the required information under "My space -> Submissions". Please use this latex template for your submission. The PDF obtained after latex compilation should be submitted as the main file, and the TEX file should be submitted as the supplementary file. If you encounter problems during the submission process you can email the local organizers (15colfrro@sciencesconf.org) with the corresponding submission information (TEX and PDF files and your choice for the minisimposia).

Deadline for presentation requests: June 15, 2022.

The posters created by young researchers will be displayed in the hall of the IMT during the conference.

A poster session is scheduled Tuesday and Thursday from 1:30 to 2:00 p.m.

The local organizers will try to provide financial support to the participants (limited funds, mainly to cover the costs of accommodation and / or meals), the priority being young researchers who give a presentation in a mini-symposium. To request financial support, please send a message to the organizers at 15colfrro@sciencesconf.org.

The subject of the message must be "funding request" and you must specify in the body of the message your name, first name, email, affiliation, your provisional arrival / departure dates and if a request for a presentation has been made (request in progress or accepted). You must also attach a Curriculum Vitae and a list of publications to the message. In addition, doctoral students must also send a letter of recommendation from their supervisor.

Deadline for financial support requests: June 15, 2022.
