Relative Manin-Mumford for semi-abelian surfaces
نویسندگان
چکیده
We show that Ribet sections are the only obstruction to the validity of the relative Manin-Mumford conjecture for one dimensional families of semi-abelian surfaces. Applications include special cases of the Zilber-Pink conjecture for curves in a mixed Shimura variety of dimension four, as well as the study of polynomial Pell equations with non-separable discriminants.

O-minimality and the André-Oort conjecture for Cn
We give an unconditional proof of the André-Oort conjecture for arbitrary products of modular curves. We establish two generalizations. The first includes the Manin-Mumford conjecture for arbitrary products of elliptic curves defined over Q as well as Lang’s conjecture for torsion points in powers of the multiplicative group. The second includes the ManinMumford conjecture for abelian varieties...

We present a new proof of the Manin-Mumford conjecture about torsion points on algebraic subvarieties of abelian varieties. Our principle, which admits other applications, is to view torsion points as rational points on a complex torus and then compare (i) upper bounds for the number of rational points on a transcendental analytic variety (Bombieri-Pila-Wilkie) and (ii) lower bounds for the deg...

متن کاملLectures 1 and 2 of “ Model
These notes are for the first two lectures of the lecture series ”Model Theory and Diophantine Geometry” by Thomas Scanlon and myself. The full series of lectures will be on the Manin-Mumford conjecture and variants. As is well-known, model-theoretic ideas, specifically definability theory in difference fields of characteristic zero, were used by Hrushovski [2] to give another proof of the Mani...
متن کاملOn Hrushovski’s Proof of the Manin-Mumford Conjecture
The Manin-Mumford conjecture in characteristic zero was first proved by Raynaud. Later, Hrushovski gave a different proof using model theory. His main result from model theory, when applied to abelian varieties, can be rephrased in terms of algebraic geometry. In this paper we prove that intervening result using classical algebraic geometry alone. Altogether, this yields a new proof of the Mani...
