Homothéties explicites des représentations -adiques
arXiv:2006.07401
Abstract
We present classical and new results on the size of the subgroup of homotheties of -adic representations associated to the torsion of an abelian variety. From these estimates, we derive uniform and explicit bounds for the Manin-Mumford problem.
