Jiří Matoušek, né le à Prague, mort le [1], est un mathématicien et informaticien théoricien tchèque. Matousek est professeur d’informatique à l’université Charles de Prague. Il est spécialiste de géométrie discrète et algorithmique et a publié de nombreux livres.

Travaux

Il résout plusieurs problèmes clés de géométrie combinatoire et d’optimisation, par exemple sur la discrépance des demi-plans ou des progressions arithmétiques, ou sur le plongement d’espaces métriques finis dans des espaces de Banach (problème de W. Johnson et J. Lindenstrauss).

Il s’intéresse aussi à la logique mathématique et avec Martin Loebl, il a amélioré un théorème de Harvey Friedman sur l’indécidabilité dans l’arithmétique de Peano d’une variante finie du théorème de Kruskal (1960)[2].

Prix et honneurs

En 1996, il est l’un des dix jeunes mathématiciens européens distingués par le prix de la Société européenne de mathématiques[3]. Dans le discours de présentation[4], la variété et la difficulté de ses résultats sont particulièrement remarqués.

En 1998, il est conférencier invité au Congrès international des mathématiciens à Berlin, avec un exposé intitulé : « Instantanés mathématiques du paysage de la géométrie computationnelle » (Mathematical Snapshots from the Computational Geometry Landscape).

En 2000, il obtient le prix des scientifiques de la Societas Scientiarum Bohemica (Société des sciences de Bohème).
