本文给出了一种计算数域上定义的曲线的雅可比行列式上重言式积分环的N 'eron-Tate高度的方法。作为例子,我们得到封闭的表达式的N 'eron-Tate高度的差异表面,阿贝尔-雅可比图像的平方曲线,和任何对称的θ因子。作为应用,我们得到了一个新的有效的正下界的本质最小值的任何阿贝尔-雅可比图像的曲线和证明,在雅可比的情况下,Autissier提出的公式有关的Faltings高度的主要极化阿贝尔品种的N 'eron-Tate高度的对称θ因子。
We develop a method to calculate the N'eron-Tate height of tautological integral cycles on jacobians of curves defined over number fields. As examples we obtain closed expressions for the N'eron-Tate height of the difference surface, the Abel-Jacobi images of the square of the curve, and of any symmetric theta divisor. As applications we obtain a new effective positive lower bound for the essential minimum of any Abel-Jacobi image of the curve and a proof, in the case of jacobians, of a formula proposed by Autissier relating the Faltings height of a principally polarized abelian variety with the N'eron-Tate height of a symmetric theta divisor.
