论文摘要

在看到有关质量分解分布的问题如何(直到最近才无法访问)的质疑是如何限制了在描述分解的图表上定义的操作员的规范之后,我们将展示如何绑定该规范。从本质上讲,该图是一个强大的局部扩展器,所有特征值都以恒定因素为界的理论最小值(即,与Ramanujan图相对应的特征值结合)。证明将使我们踏上从图理论到线性代数以及数字的几何形状,再到图理论的几何形状,并通过一般的筛子辅助。这是一张说明书;完整的证明已作为M. radziwi \ {l} \ {l}的关节预印本。

After seeing how questions on the finer distribution of prime factorization -- considered inaccessible until recently -- reduce to bounding the norm of an operator defined on a graph describing factorization, we will show how to bound that norm. In essence, the graph is a strong local expander, with all eigenvalues bounded by a constant factor times the theoretical minimum (i.e., the eigenvalue bound corresponding to Ramanujan graphs). The proof will take us on a walk from graph theory to linear algebra and the geometry of numbers, and back to graph theory, aided, along the way, by a generalized sieve. This is an expository paper; the full proof has appeared as a joint preprint with M. Radziwi\{l}\{l}.
