关于非负整数$x$和$y$的重复表示为$2^x + 3^y$

On duplicate representations as $2^x + 3^y$ for nonnegative integers $x$ and $y$

Douglas Edward Iannucci

摘要:

我们证明了一个猜想张贴在网上百科全书的序列,即有正好五个正整数,可以写在一个以上的方式作为总和的非负的权力2和非负的权力3。两个幂都为正的情况可以从贝内特定理得出。我们使用初等方法证明零指数是允许的情况。

英文摘要:

We prove a conjecture posted in the Online Encyclopedia of Integer Sequences, namely that there are exactly five positive integers that can be written in more than one way as the sum of a nonnegative power of 2 and a nonnegative power of 3. The case for both powers being positive follows from a theorem of Bennett. We use elementary methods to prove the case where zero exponents are allowed.
