Preventing Exceptions to Robins InEquality

Abstract

For sufficiently large n Ramanujan gave a sufficient condition for the truth Robin's InEquality X(n):=σ(n)nlnlnn<eγX(n):=\frac{\sigma(n)}{n\ln\ln n}<e^{\gamma} (RIE). The largest known violation of RIE is n8=5040n_8=5040. In this paper Robin's multipliers are split into logarithmic terms L\mathcal{L} and relative divisor sums G\mathcal{G}. A violation of RIE above n8n_{8} is proposed to imply oscillations that cause G\mathcal{G} to exceed L\mathcal{L}. To this aim Alaoglu and Erd\H{o}s's conjecture for the CA numbers algorithm is used and the paper's key points are in section 4.2
