Hauteurs normalisées des sous-variétés de produits de modules de Drinfeld
Published online by Cambridge University Press: 04 December 2007
Abstract
After establishing some important results on the usual height of projective varieties in positive characteristic, we construct a normalized height for subvarieties of products of Drinfeld modules and investigate its properties. In case the Drinfeld modules are pairwise isogeneous, we obtain in particular that the normalized height vanishes exactly on torsion varieties, that is on translates of sub-T-modules by torsion points.
