Elementary embeddings in torsion-free hyperbolic groups
We describe first-order logic elementary embeddings in a torsion-free hyperbolic group in terms of Sela’s hyperbolic towers. Thus, if embeds elementarily in a torsion free hyperbolic group , we show that the group can be obtained by successive amalgamations of groups of surfaces with boundary to a free product of with some free group and groups of closed surfaces. This gives as a corollary that an elementary subgroup of a finitely generated free group is a free factor. We also consider the...

Éléments réguliers et représentations de Gelfand-Graev des groupes réductifs non connexes
Soient un groupe algébrique réductif connexe défini sur et l’endomorphisme de Frobenius correspondant. Soit un automorphisme rationnel quasi-central de . Nous construisons ci-dessous l’équivalent des représentations de Gelfand-Graev du groupe , lorsque est unipotent et lorsqu’il est semi-simple. Nous montrons de plus que ces représentations vérifient des propriétés semblables à celles vérifiées par les représentations de Gelfand-Graev dans le cas connexe en particulier par rapport aux...

Embedding -homogeneous latin trades into abelian -groups
Let be a partial latin square and be a latin square with . We say that is a latin trade if there exists a partial latin square with such that is a latin square. A -homogeneous latin trade is one which intersects each row, each column and each entry either or times. In this paper, we show the existence of -homogeneous latin trades in abelian -groups.
