 Orateur(s) Jing Yu - , Titre On the reductions of non-torsion points Date 13/05/2002 Horaire 14:00 à 16:00 Diffusion Résume Given a commutative algebraic group $G$ definedover a global field, and a non-torsion rationalpoint $P$ on it, we are interested in the ordersof the reduction of that point modulo variousprimes. In particular, we ask whether theoccurred orders will cover almost all positiveintegers. Replacing algebraic group by Drinfeldmodules, analogous questions can also be asked.The connection of these problems with linearforms in logarithms will be explained. Salle Adresse
