International Mathematics Research NoticesAbstract We showthat for every integer $k\geqslant 3$ the set of Turán densities of $k$-uniform hypergraphs has an accumulation point in $[0,1)$. In particular, $1/2$ is an accumulation point for the set of Turán densities of $3$-uniform hypergraphs.

Hypergraphes de Petersen! Hypergraphes de Moore?
Discrete Mathematics, 1993 RésuméOn étudie ici des sous structures des plan projectifs finis Pg(2,n) oú n est impair. Dans ceux-ci les (n + 1)-arcs induisent une décomposition canonique.Soit E l'ensemble des points, D celui des droites, appelons X l'ensemble des points d'un (n+1)-arc.
