A Study of @-numbers
Abstract
This paper deals more generally with @-numbers defined as follows: Call `\textit{alpha number}' of order , (denote its family by @) any satisfying where is sum of divisors function and , the set of \textit{quaternions}. Specifically, if integer is such that with (where is the number of distinct prime factors of , is the number of factors of ), then is respectively called strong, weak or very weak alpha number. We give some examples and conjecture that there is no odd strong alpha number of order . The truthfulness of this assertion implies that there is no odd perfect and certain odd multi-perfect numbers. We give all the strong even alpha numbers of order below and then show that there is no odd strong alpha number of order below , using some of our results motivated by some results of Ore and Garcia. With computer search this bound can easily be surpassed. In this paper, using Rossen, Schonfield and Sandor's inequalities, in addition to the aforementioned definition, we also bound the quotient of order , though a very weak bound. Some areas for future research are also pointed out as recommendations.
