On sums of the small divisors of a natural number

Douglas E. Iannucci

We consider the positive divisors of a natural number that do not exceed its square root, to which we refer as the {\it small divisors\/} of the natural number. We determine the as…

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

Douglas Edward Iannucci

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 s…
