Résumé
Abstract

On donne une approche algébrique à l’étude des paires de Hitchin et on démontre le théorème du produit tensoriel pour des paires de Hitchin semistables sur les courbes projectives lisses définies sur un corps algébrique clos de caractéristique nulle ou bien de caractéristique $p$ , où $p$ désigne un nombre premier borné. On démontre aussi un théorème similaire pour des paires de Hitchin polystables.

We give an algebraic approach to the study of Hitchin pairs and prove the tensor product theorem for Higgs semistable Hitchin pairs over smooth projective curves defined over algebraically closed fields of characteristic zero and characteristic $p$ , with $p$ satisfying some natural bounds. We also prove the corresponding theorem for polystable Hitchin pairs.
