Abstract

In this paper, we investigate the set S(n) of positive integer solutions of the title Diophantine equation. In particular, for a given n we prove boundedness of the number of solutions, give precise upper bound on the common value of σ2(X¯n) and σn(X¯n) together with the biggest value of the variable xn appearing in the solution. Moreover, we enumerate all solutions for n16 and discuss the set of values of xn/xn1 over elements of S(n).

关于 Diophantine 方程 σ2(X¯n) = σn(X¯n)
在本文中,我们研究了标题 Diophantine 方程的正整数解集 S(n)。特别是,对于给定的 n,我们证明了解的有界性,给出了 σ2(X¯n)和 σn(X¯n)的公共值以及解中出现的变量 xn 的最大值的精确上限。此外,我们列举了 n≤16 的所有解,并讨论了 S(n) 元素上 xn/xn-1 的值集。
