Abstract

Hardy conjectured that the error term arising from approximating the number of lattice points lying in a radius- $R$ disc by its area is $O (R^{1 / 2 + o (1)})$ . One source of support for this conjecture is a folklore heuristic that uses i.i.d. random variables to model the lattice points lying near the boundary and square root cancellation of sums of these random variables. We examine this heuristic by studying how these lattice points interact with one another and prove that their autocorrelation is determined in terms of a random model. Additionally, it is shown that lattice points near the boundary which are “well separated” behave independently. We also formulate a conjecture concerning the distribution of pairs of these lattice points.

绕过高斯圆问题：哈代猜想与圆附近网格点的分布

哈代猜想，用一个半径为 R $R$ 的圆盘的面积来近似位于该圆盘中的晶格点的数量，其误差项为 O ( R 1 / 2 + o ( 1 ) ) $O(R^{1/2+o(1)})$。支持这一猜想的一个来源是一种民间启发式，它使用 i.i.d. 随机变量来模拟位于边界附近的晶格点，并对这些随机变量的和进行平方根抵消。我们通过研究这些网格点如何相互影响来检验这一启发式，并证明它们的自相关性是由随机模型决定的。此外，我们还证明了边界附近 "分离得很好 "的网格点的独立行为。我们还提出了关于这些晶格点的成对分布的猜想。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
