Action de groupe et semi-stabilité du produit tensoriel
Résumé
We prove a conjecture of Coulangeon and Nebe which is a special case of a conjecture of Bost. Given two semi-stable metrized vector spaces over a number field we show that their tensor product is also semi-stable whenever there is a group acting on one of the spaces in a multiplicity-free way.
