Solving the Odd Perfect Number Problem: Some New Approaches
Odd perfect number Euler factor inequalities OPN components non-injective and non-surjective mapping
2012/6/29
A conjecture predicting an injective and surjective mapping $X = \displaystyle\frac{\sigma(p^k)}{p^k}, Y = \displaystyle\frac{\sigma(m^2)}{m^2}$ between OPNs $N = {p^k}{m^2}$ (with Euler factor $p^k$)...
