Preface

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.

The invited speakers were

Abdelmalek Abdesselam (University of Virginia, Charlottesville)
"Feynman diagrams in elimination theory and classical invariant theory"

and

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