Jean-Louis Koszul (French: [kɔsyl]; January 3, 1921 – January 12, 2018) was a French mathematician, best known for studying geometry and discovering the Koszul complex. He was a second generation member of Bourbaki.

In the late 1950’s, J. L. Koszul visited the University of São Paulo and taught three courses whose magistral notes were published there [1] [2] [3]. In 1986 he visited again to give one of the inaugural conferences at the Institutos de Estudos Avançados of the University of São Paulo. The purpose of this session is to rescue his influence from the historic and scientific viewpoint. This meeting is part of the 2nd Workshop SPJM and will include a round-table with some members of the Editorial Board.

The São Paulo Journal of Mathematical Sciences (SPJM) is an international peer-reviewed journal that endeavors to publish high-quality original research articles and well-written expository articles on a broad range of theoretical and applied areas of mainstream mathematics that are of interest to a substantial number of its readers, including those areas of computer science and statistics with significant mathematical content. All submissions are carefully managed by a distinguished editorial board and checked for correctness and suitability for publication
