Preventing Exceptions to Robins InEquality

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

Ramanujan's Heirs

Prof. Dr. Richard Dipper initiated the Summer School 1998 with Dr. Bernd Ackermann at the University of Stuttgart a year after Ramanujan's "lost notebook" had been published. The prime numbers needed in the representation theory of $\mathfrak{S}_{n}$ motivated me to think about the notebook, too. This article summarizes these ideas.
