具有最少项数的同方幂和相等

Equal Sums of Like Powers with Minimum Number of Terms

Ajai Choudhry

摘要:

本文研究丢番图系统$\sum_{i=1}^{s_1} x_i^r=\sum_{i=1}^{s_2} y_i^r,\, r=1,\,2,\,\ldots,\,k, $,其中$s_1$和$s_2$是整数,使得两边的项数之和,即$s_1+s_2,$尽可能小.我们定义$β(k)$为$s_1+s_2$的最小值,使得该丢番图系统存在非平凡解。当$k < 6$时,我们找到了这个丢番图系统的非平凡整数解,从而证明了$β(2) =4,\;\, β(3) = 6,\;\, 7 \leq β(4) \leq 8$和$8 \leq β(5) \leq 10$ .

英文摘要:

This paper is concerned with the diophantine system, $\sum_{i=1}^{s_1} x_i^r=\sum_{i=1}^{s_2} y_i^r,\, r=1,\,2,\,\ldots,\,k, $ where $s_1$ and $s_2$ are integers such that the total number of terms on both sides, that is, $s_1+s_2,$ is as small as possible. We define $β(k)$ to be the minimum value of $s_1+s_2$ for which there exists a nontrivial solution of this diophantine system. We find nontrivial integer solutions of this diophantine system when $k < 6$, and thereby show that $β(2) =4,\;\, β(3) = 6,\;\, 7 \leq β(4) \leq 8$ and $8 \leq β(5) \leq 10$.
