两个平方和之间的巨大差距

Large gaps between sums of two squares

A. B. Kalmynin, S. V. Konyagin

摘要:

设$\mathcal S=\{s_1<s_2<s_3<\ldots\}$是所有自然数的序列,这些自然数可以表示为两个整数的平方和。对于$X\ge2$,我们用$g(X)$表示不超过$X$的$\mathcal S$的连续元素之间的最大间隙。我们证明了$X \to +\infty$的下界$$g(X)\geq \left(\frac{390}{449}-o(1)\right)\ln X$$持有。这个估计是R最近估计的两倍。迪特曼和C.埃尔肖尔茨。

英文摘要:

Let $\mathcal S=\{s_1<s_2<s_3<\ldots\}$ be the sequence of all natural numbers which can be represented as a sum of two squares of integers. For $X\ge2$ we denote by $g(X)$ the largest gap between consecutive elements of $\mathcal S$ that do not exceed $X$. We prove that for $X \to +\infty$ the lower bound $$g(X)\geq \left(\frac{390}{449}-o(1)\right)\ln X$$ holds. This estimate is twice the recent estimate by R. Dietmann and C. Elsholtz.
