Vojta不等式与曲线上有界次数的有理积分点

Vojta's Inequality and Rational and Integral Points of Bounded Degree on Curves

Aaron Levin

摘要:

设C_1xC_2中的C是两条曲线C_1和C_2的乘积中的(d_1,d_2)型曲线。设d为正整数。本文证明了:如果满足一个包含d_1,d_2,d以及曲线C_1,C_2和C的亏格的不等式,则C(\kbar)中的点集P对任意数域k都是有限的,其中[k(P):k]<=d.我们证明了C上有界次数整点的一个类似结果。这些结果是作为Vojta的一个不等式的结果而得到的,Vojta的不等式将Roth-Wirsing定理推广到曲线上。

英文摘要:

Let C in C_1xC_2 be a curve of type (d_1,d_2) in the product of the two curves C_1 and C_2. Let d be a positive integer. We prove that if a certain inequality involving d_1, d_2, d, and the genera of the curves C_1, C_2, and C is satisfied, then the set of points P in C(\kbar) with [k(P):k]<=d is finite for any number field k. We prove a similar result for integral points of bounded degree on C. These results are obtained as consequences of an inequality of Vojta which generalizes the Roth-Wirsing theorem to curves.
