AI总结:

本文从理论和实验角度研究丢番图方程$x^3±y^3=a^k±b^k$,证明$k=4,6$时方程有无穷多互质正整数解,计算了$k=5,7$且$\text{max}\{a,b\}≤50000$的全部互质正整数解。

摘要:

本文从理论和实验角度研究标题中的丢番图方程。特别地,证明当$k=4,6$时,无论符号如何选择,方程均有无穷多组互质正整数解;对$k=5,7$及所有符号组合,计算了满足$\text{max}\{a,b\}≤50000$的全部互质正整数解$(x,y,a,b)$。

英文摘要:

In this note we consider the title Diophantine equation from both theoretical as well as experimental point of view. In particular, we prove that for $k=4, 6$ and each choice of the signs our equation has infinitely many co-prime positive integer solutions. For $k=5, 7$ and all choices of the signs we computed all co-prime positive integer solutions $(x, y, a, b)$ satisfying the condition $\op{max}\{a, b\}\leq 50000$.
