On the Ratio of the Sum of Divisors and Euler's Totient Function II
J. Integer Seq., 2014 Summary: We find the form of all solutions to \(\varphi (n)/ \sigma (n)\) with three or fewer prime factors, except when the quotient is 4 and \(n\) is even. For Part I see J. Integer Seq. 16, No. 8, Article 13.8.8, 16 p. (2013; Zbl 1342.11008).

Distribution of values of general Euler totient function
Journal of Mathematical Analysis and ApplicationsLet $Φ_k(n)=|\{ (x_1, x_2, \cdots, x_k)\in \left(\mathbb{Z}/n\mathbb{Z}\right)^k; \ \gcd(x_1^2+x_2^2+ \cdots+ x_k^2, n)=1\}|$ be a general totient function introduced first by Caldéron et. al. Motivated by the classical works of Schoenberg, Erdős, Bateman and Diamond on the distribution of $Φ_1(n)$, we prove results on the joint distribution of $Φ_k(n)$
