Jean-Louis Koszul passed away

[Geo-Sci-Info]

Dear all,

Profound sadness on the passing of Professeur Jean-Louis Koszul (1921-2018+), Friday January 12th 2018, Geometer, Henri Cartan's PhD student, member of Bourbaki, who honored us with his presence at Mines GSI'13 conference for Hirohiko Shima keynote on Geometry of Hessian Structures related to Koszul forms and Koszul-Vinberg Characteristic Function.
His works on convex homogeneous cones are at the foundation of Information Geometry theory.
