Michel Las Vergnas

Michel Las Vergnas (January 11, 1941 – January 19, 2013) was a French mathematician associated with Pierre-and-Marie-Curie University in Paris, and a research director emeritus at the Centre national de la recherche scientifique.[1][2]

Las Vergnas earned his Ph.D. in 1972 from Pierre-and-Marie-Curie University, under the supervision of Claude Berge.[3] He was one of the founders of the European Journal of Combinatorics, which began publishing in 1980.[4]

His initial research was in graph theory, and particularly in the theories of matching and connectivity.[1] Beginning in 1975, he became one of the pioneers of the theory of oriented matroids,[1][5][6] and since that time he was interested in connections between combinatorics and geometry.[1]

A workshop on combinatorial geometry, held in Marseilles in April 2013, was dedicated to his memory.[7]
