Subsets of colossally abundant numbers

Xiaolong Wu

Let $G (n) = σ (n) / (n lo g lo g n)$ . Robin made hypothesis that $G (n) < e^{γ}$ for all integer $n > 5040$ . This article divides all colossally abundant numbers in to three disjoint subsets…

Properties of counterexample to Robin hypothesis

Xiaolong Wu

Let $G (n) = σ (n) / (n lo g lo g n)$ . Robin made hypothesis that $G (n) < e^{γ}$ for all integer $n > 5040$ . If there exists counterexample to Robin hypothesis, then there must exist finite n…
