Preface

The 44th Meeting of the Séminare Lotharingien de Combinatoire took place from March 6 to March 9, 2000 in the splendid Domaine Saint-Jacques on a small mountain not far from Strasbourg. As was the case for previous meetings at this place, all participants enjoyed (I mean, in addition to the talks, of course) the pleasant atmosphere, the meals (!), and the evenings with music, even if it cannot be denied that the piano needs some serious overhaul now ...

The main talks were given by PIERRE CARTIER (École Normale Supérieure) and HERB WILF (University of Pennsylvania). Pierre Cartier presented us a beautiful introduction into the fascinating world of "Multizeta values and shuffle algebra". It is unfortunate that no written version is available. Herb Wilf on the other hand presented, in his distinctive elegant style, "Recent results on integer partitions". You are invited to consult these lecture notes and this article for written material.

Further talks were given by:

Marilena Barnabei: "Generalized circulant matrices"
Francesco Brenti: "Dyck partitions"
Sylvie Corteel: "The combinatorics of Ramanujan's ₁psi₁ summation"
Frederic Jouhet: "Sur une identité de Lascoux-Lassalle en théorie des partitions"
Bodo Lass: "Dénombrement des couplages"
Marc van Leeuwen: "Jeu de taquin for Littelmann's paths"
Anne Micheli: "Enumeration of rooted multi-colored maps"
Hoang Ngoc Minh: "De l'algèbre des fonctions zeta de Riemann (multivariées) à l'algèbre des fonctions zeta d'Hurwitz (multivariées)"
Paolo Papi: "Combinatorics of ad-nilpotent ideals of Borel subalgebras"
Marko Petkovsek: "Gambler's Ruin Problem in several dimensions"
Amitai Regev: "The Vershik-Kerov theory and combinatorial identities"
Gilles Schaeffer: "On the number of corner cut partitions"
Einar Steingrímsson: "A new approach to (Euler-)Mahonian permutation statistics, leading to a classification of most known such statistics"
Frederic Toumazet: "Generic products for Sp(2n,R) and SO*(2n)"
Burkhard Zimmermann: "WZ forms in hypergeometric summation"
