About Jean-Marie Souriau
- Jean-Marie Souriau (3 June 1922 – 15 March 2012) was a French mathematician, known for works in symplectic geometry, in which he was one of the pioneers.
- He published several works, a treatise on linear algebra [Sou64a], a treatise on relativity [Sou64b] and a treatise on symplectic mechanics [Sou70].
- He developed the symplectic aspects of classical and quantum mechanics.
- He contributed to the introduction or the development of many important concepts, such as the coadjoint action and the coadjoint orbits of a group on its moment space, which led in particular to the first geometric interpretation of spin at a classical level.
- He introduced the moment map, he suggested a program of geometric quantization, he gave a classification of the homogeneous symplectic manifolds, known as the Kirillov-Kostant-Souriau theorem.
- Finally, he proposed a new approach to differential geometry by means of diffeologies. He was educated at the École Normale Supérieure in Paris, and spent most of his career as a Professor of Mathematics at the University of Provence in Marseille.
