The 68th Meeting of the Séminaire Lotharingien de Combinatoire took place from March 25 to March 28, 2012 at the Domaine Saint-Jacques, Saint-Nabor, France, which had been a standard place for the seminar for twenty years. The seminar hosted a special session on Combinatorial Physics, organized by Gérard Duchamp and Adrian Tanasa.

"Feynman diagrams in elimination theory and classical invariant theory"


Gilles Schaeffer (CNRS, École Polytechnique, Paris)
"Trees, maps, and the combinatorics of Hurwitz numbers"
