W​ith a particular interest in topological graphs and labyrinths, Pierre Rosenstiehl’s mathematical life was full of interactions with social sciences and art. 
As an echo to his novel « Le Labyrinthe des jours ordinaires » and to his lifelong interest, this workshop will celebrate the « Labyrinth of Combinatorics ».
