结合Arakelov理论和Belyi定理,我们得到数域上代数曲线上因子的Néron-Tate高度配对的值本质上是与模群PsL_2(ℤ)的有限指数子群有关的散射常数的线性组合.
Abstract.Combining Arakelov theory with Belyi’s theorem we derive that the values of the Néron-Tate height pairing for divisors on algebraic curves defined over number fields are essentially given by linear combinations of scattering constants associated to finite index subgroups of the modular group PSL2(ℤ).
