周期解析集中的有理点与Manin-Mumford猜想

Rational points in periodic analytic sets and the Manin-Mumford conjecture

Jonathan Pila, Umberto Zannier

摘要:

给出了关于阿贝尔簇的代数子簇上扭点的Manin-Mumford猜想的一个新证明.我们的原则,承认其他应用程序,是把扭点作为有理点在一个复杂的环面,然后比较(一)上界的数量有理点上的超越解析品种(Bjueri-Pila-Wilkie)和(二)下界的程度的一个扭点(Masser),采取共轭。为了能够处理(i),我们讨论(Thm。2.1)摘要解析簇中的半代数曲线假设在满格上平移不变性,这是一个具有独立动机的课题。

英文摘要:

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 degree of a torsion point (Masser), after taking conjugates. In order to be able to deal with (i), we discuss (Thm. 2.1) the semi-algebraic curves contained in an analytic variety supposed invariant for translations by a full lattice, which is a topic with some independent motivation.
