On some properties of the Eulerʹs factor of certain odd perfect numbers Original Research Article

Let n=πα32βQ2β be an odd positive integer, with π prime, π≡α≡1 (mod 4), Q squarefree, (Q,π)=(Q,3)=1. It is shown that: if n is perfect, then σ(πα)≡0 image. Some corollaries concerning the Eulerʹs factor of odd perfect numbers of the above mentioned form, if any, are deduced.
