Abstract
|
In 1996 Erdős conjectured that the set
defined as the sums of distinct powers of 3 and distinct powers of 4 has
positive asymptotic density. We investigate some structure properties of
this set. We also prove some asymptotic estimates for its counting function
. In particular
we prove that

improving an old estimate of Melfi.
