modifier

László Fejes Tóth (-) est un mathématicien hongrois spécialiste en géométrie.

Travaux

Il a démontré le théorème du nid d'abeille sous l'hypothèse de convexité des tuiles du pavage. Persuadé que le théorème resterait vrai sans cette hypothèse il ne parvint néanmoins pas à le démontrer, affirmant que cela soulèverait des « difficultés considérables »[1]. Il est également connu pour son travail sur les empilements de sphères ; László Fejes Tóth a démontré[2] en 1953 que la conjecture de Kepler pouvait être réduite à un problème à un nombre fini de paramètres.

Professeur à l'Institut de recherches mathématiques Alfréd-Rényi (Rényi Alfréd Matematikai Kutatóintézet) de Budapest, il en a pris la tête de 1970 à 1982 à la mort d'Alfréd Rényi.
