三元模素幂二次同余方程小解的渐近性

Asymptotic behavior of small solutions of quadratic congruences in three variables modulo prime powers

Stephan Baier, Anup Haldar

摘要:

设$p>5$是一个固定素数,并假定$α_1,α_2,α_3$与$p$互质。研究了$α_1x_1^2+α_2x_2^2+α_3x_3^2\equiv 0\bmod{q}$与$q=p^n$形式的同余的小解的渐近性态,其中$\max\{|x_1|,|x_2|,|x_3|\}\le N$和$(x_1x_2x_3,p)=1$ . (In事实上,我们考虑这个问题的平滑版本。)如果$α_1,α_2,α_3$是固定的,并且$n\rightarrow \infty$是固定的,我们在条件$N\gg q^{1/2+\varepsilon}$下建立了一个渐近公式(从而证明了这种解的存在性).如果这些系数被允许与$n$变化,我们表明,这个公式成立,如果$N\gg q^{11/18+\varepsilon}$。后者应比较结果希思布朗谁建立了存在的非零解决方案的条件下$N \gg q^{5/8+\varepsilon}$的奇数平方模$q$。

英文摘要:

Let $p>5$ be a fixed prime and assume that $α_1,α_2,α_3$ are coprime to $p$. We study the asymptotic behavior of small solutions of congruences of the form $α_1x_1^2+α_2x_2^2+α_3x_3^2\equiv 0\bmod{q}$ with $q=p^n$, where $\max\{|x_1|,|x_2|,|x_3|\}\le N$ and $(x_1x_2x_3,p)=1$. (In fact, we consider a smoothed version of this problem.) If $α_1,α_2,α_3$ are fixed and $n\rightarrow \infty$, we establish an asymptotic formula (and thereby the existence of such solutions) under the condition $N\gg q^{1/2+\varepsilon}$. If these coefficients are allowed to vary with $n$, we show that this formula holds if $N\gg q^{11/18+\varepsilon}$. The latter should be compared with a result by Heath-Brown who established the existence of non-zero solutions under the condition $N \gg q^{5/8+\varepsilon}$ for odd square-free moduli $q$.
