SUMMARY:On the quantitative Manin-Mumford conjecture
DESCRIPTION:Exposé dans le cadre du séminaire de théorie des nombres \n\n\n\nOrateur : Robert Wilms \n\n\n\nThe Manin-Mumford conjecture\, proved by Raynaud in 1983\, states that there are only finitely many torsion points on the embedding of a curve of genus g>1 into its Jacobian. In the first part of the talk\, I will show that over function fields there are at most 16g²+32g+124 such points. This is joint work with Looper and Silverman. In the second part\, I will discuss recent progress on an analogous result in the case of number fields.
