Preface

The 52nd Séminaire Lotharingien de Combinatoire took place in

Domaine Saint-Jacques, 67530 Ottrott, France,

from Sunday, March 28, 2003 (evening) to Wednesday, March 31, 2004 (afternoon).

This meeting of the Séminaire Lotharingien hosted a special session, the LascouxFest, celebrating the 60th birthday of Alain Lascoux. The event, which attracted 67 participants from some ten countries, was intended as a surprise for Alain. After one day of regular talks, the second day opened with a lecture by Piotr PRAGACZ reviewing the mathematical work of Alain. It was followed by fifteen invited talks of high quality, and the seminar ended with a talk by Alain himself.

The organizing institution was the University of Marne-la-Vallée (J. Désarménien, J.-G. Luque, J.-Y. Thibon).

The invited lectures in the LascouxFest were the following:

Christine BESSENRODT: On some properties of the character tables of Sn, \tilde Sn and An
Francesco BRENTI: A Foata-Schützenberger type theorem for the hyperoctahedral group
