Séminaire Lotharingien de Combinatoire, B58pref (2007), 1 p.

Riccardo Biagioli, Frédéric Jouhet and Jiang Zeng


The 58th Séminaire Lotharingien de Combinatoire was held from March 18 to 21, 2007 at Domaine des Hautannes, St.Germain au Mont d'Or, a small town in the north of Lyon.

The main speakers of this session were:

Frédéric CHAPOTON (Université Claude Bernard Lyon 1)
Hjalmar ROSENGREN (Chalmers University of Technology).

They gave, respectively, three lectures on the topics "Operads and Algebraic Combinatorics of Trees" and "Applications of Pfaffians in Number Theory and Combinatorics."

The seminar was followed by a "Groupe de travail jeunes chercheurs en Combinatoire Algébrique" within the program GDR - Informatique Mathématique, March 21-22, 2007.

Three introductory lectures were given by:

Olga AZENHAS: Fundamental symmetry identical involutions: a conjecture by Pak and Vallejo

Eric BABSON: Moduli of marked representations of path algebras

Roland BACHER: On the interpolation groups

Alexander BURSTEIN: On some properties of permutation tableaux
