论文摘要
对于相对主要的整数$ a $和$ b $，均大于一个和奇数整数$ c $，最多有两个解决方案在正整数中$（x，y，z）$ to equation $ a^x + b^y = c^z $。有无限的$（a，b，c）$提供了两种解决方案。
For relatively prime integers $a$ and $b$ both greater than one and odd integer $c$, there are at most two solutions in positive integers $(x,y,z)$ to the equation $a^x + b^y = c^z$. There are an infinite number of $(a,b,c)$ giving exactly two solutions.
