Talk:Jordan's totient function

Condition
In the Dirichlet series, the condition is that R(s) is bigger than k+1.

Two arguments
When it is said that the function is multiplicative, it should be said that it is a multiplicative function of n. It has two arguments. — Preceding unsigned comment added by 86.179.201.218 (talk) 14:57, 24 January 2014 (UTC)
 * No. It is said that the function $$J_ k$$, which has one argument, n, is multiplicative. Sapphorain (talk) 16:33, 24 January 2014 (UTC)
 * On the face of it, the function has two arguments, k and n. — Preceding unsigned comment added by 5.249.68.195 (talk) 10:06, 15 March 2014 (UTC)
 * No. As specified in the very first sentence, k is some positive integer. The subscript k in $$J_ k$$ is part of the name of the function, and is not an argument of it. Sapphorain (talk) 16:20, 18 March 2014 (UTC)
 * Except that "$$J_k$$ is multiplicative" is not what was said. Fixed now. --Daira Hopwood ⚥ (talk) 13:14, 22 October 2018 (UTC)
