Talk:Picard group

From Wikipedia, the free encyclopedia

[edit] Alternate definition/Disambiguation

I'm staring at an alternate definition of the Picard group as PSL(2,Z[i]), with Z[i] the gaussian integers. I can't tell at all if this is somehow related to the Picard group defined in this article. Any clue? Problem I'm dealing with is a link I just added from Fuchsian group to here. linas 01:08, 6 Jun 2005 (UTC)
