簇的模空间上整点的稀疏性

Sparsity of Integral Points on Moduli Spaces of Varieties

Jordan S. Ellenberg, Brian Lawrence, Akshay Venkatesh

摘要:

设$X$是数域上的一个拟射影簇,(在通过到$\mathbb{C}$之后)允许Hodge结构的一个几何变化,其周期映射具有零维纤维.那么$X$的整点是稀疏的:高度为$\leq B$的这些点的数量增长得比$B$的任何正幂都慢。例如,齐次积分多项式在固定数量的变量和次数,判别式只能被一组固定的素数整除,被认为是稀疏的整数线性替换。

英文摘要:

Let $X$ be a quasi-projective variety over a number field, admitting (after passage to $\mathbb{C}$) a geometric variation of Hodge structure whose period mapping has zero-dimensional fibers. Then the integral points of $X$ are sparse: the number of such points of height $\leq B$ grows slower than any positive power of $B$. For example, homogeneous integral polynomials in a fixed number of variables and degree, with discriminant divisible only by a fixed set of primes, are sparse when considered up to integral linear substitutions.
