关于用二次型表示二次型

On the representation of quadratic forms by quadratic forms

Rainer Dietmann, Michael Harvey

摘要:

利用圆的方法,证明了对于一个固定的定积分二次型$A$,当$A$的维数与$B$的维数和$B$的连续最小值的最大比足够大时,由$A$表示正定定积分二次型$B$的个数的期望渐近公式成立.并且假设$B$在$A$方面足够大。

英文摘要:

Using the circle method, we show that for a fixed positive definite integral quadratic form $A$, the expected asymptotic formula for the number of representations of a positive definite integral quadratic form $B$ by $A$ holds true, providing that the dimension of $A$ is large enough in terms of the dimension of $B$ and the maximum ratio of the successive minima of $B$, and providing that $B$ is sufficiently large in terms of $A$.
