给出了交换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,这承认其他应用,是把扭点视为合理的点在一个复杂的环面,然后比较(i)上限的数量合理的点在一个超越的解析簇(Bjerieri-Pila-Wilkie)和(ii)下界的程度的一个扭点(Masser)后,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对于满格的平移是不变的,这是一个有着独立动机的课题。
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.
