Our colleague Frédéric Maffray suddenly passed away in the summer 2018. We organized a scientific conference to pay homage to Frédéric. The conference took place in Grenoble on 2-4 September 2019, one year after his passing.

Frédéric Maffray was a researcher in discrete mathematics and held the position of “directeur de recherche” with the CNRS. He authored more than 125 scientific articles, published in international journals at the highest level. He collaborated with nearly a hundred researchers of all nationalities. His research focus was graph theory, notably the study of structural properties of graphs (perfect graphs and more generally graphs characterized by forbidden subgraphs) that permit the efficient resolution of classic optimization problems such as graph coloring. Frédéric was a member of the Combinatorial Optimization team at the G-SCOP laboratory and was a CNRS researcher in Grenoble since 1990. He was one of the most productive and esteemed graph theorists in France.

This conference, open to all and without registration fees, reunited his colleagues to celebrate the significant scientific contribution of Frédéric Maffray as well as his remarkable personal qualities. The program consisted of invited presentations delivered by his collaborators, former students and close colleagues. The slides of some of the talks, as well as some pictures taken during the conferences, are available here.
