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)[reply]

No. It is said that the function

J_{k}

, which has one argument, n, is multiplicative. Sapphorain (talk) 16:33, 24 January 2014 (UTC)[reply]

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)[reply]

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)[reply]

Except that "

J_{k}

is multiplicative" is not what was said. Fixed now. --Daira Hopwood ⚥ (talk) 13:14, 22 October 2018 (UTC)[reply]
