Colloque International de Théories Variationnelles (CITV) 2020

    SOURIAU COLLOQUIUM - Jaca, October 25th, 2020 to October 30th, 2020


The Souriau Colloquium, initially planned in June at Jaca, was postponed in October. 
Unfortunately, we were too optimistic and the negative evolution of the Covid-19 pandemic in Spain forces us to cancel definitively the 2020 edition of the Colloquium. 
The persons already registered will be refunded.
We apologize for any inconvenience that this cancellation may cause.
Expecting the situation will improve meanwhile, we hope to be able to welcome you for the 2021 edition at Alghero in Sardinia. 
Take care of you and your family.

Jean-Marie Souriau ( and, born on 3 June 1922 and dead on 15 March 2012, was a French mathematician, known for works in symplectic geometry, in which he was one of the pioneers.

He has left us not solely a master piece of scientific work through his treatises on dynamical systems, relativity and quantum mechanics but Jean-Marie Souriau  –the professor and the human person–  has also given us a sound philosophical vision of the world through his last book, “Grammaire de la nature”.

Originally founded in 1956 by Jean-Marie Souriau, his doctoral students and friends, re-launched by Claude Vallée in 1996, the Colloquium entitled “Colloque International de Théories Variationnelles” (CITV) provides today an informal setting to present and discuss the state-of-the-art and the most recent findings concerning Mathematics, Physics, Mechanics and their interactions.

Every year during a week, the CITV brings together a small group of participants hoping to work within the founder’s spirit. In marked contrast to standard Colloquia, the CITV’s style is completely informal:

-        The schedule is prepared day-to-day and, if necessary, the talk durations may be adjusted under way.

-        Preference is given to present ideas on the blackboard even if modern video presentations are also allowed.

-        Emphasis is put on scientific maturity and creative ideas as opposed to technicalities.

-        A large time is devoted to questions, discussion and exchange of ideas.

-        The spectrum of topics being very broad, a special attention is paid to present advanced concepts in simple terms for people with strong scientific background but the non-specialists of the topic.

-        The oral transmission of the knowledge is preferred –but not opposed– to modern communication based on paper publication.

-        Epistemological talks are sometimes given in the evening and also open to accompanying persons.

-        The social program is not reserved for accompanying persons but convivial interludes are scheduled in the afternoon for scientific participants sharing cultural visits and excursions with them.
