Explain why its a Dirichlet ring, and not a field_(mathematics). Naively, it seems to have additive and multiplicative units and inverses. linas 05:00, 6 Jan 2005 (UTC)

Because only arithmetic functions for which f(1) is not 0 have inverses. I have clarified this in the article. Gandalf61 10:25, May 21, 2005 (UTC)
