Langlands group vs Langlands dual group
[edit]There is something called the Langlands group, so this article should refer to it. The common name for the Langlands dual group is simply the L-group. I think what is currently here should be in an article called L-group, and the article Langlands group should be about the Langlands group of a global/local field which is a (conjectural) extension of the Weil group of a global/local field by a compact group. See for example the nice article of Arthur's http://www.claymath.org/cw/arthur/pdf/automorphic-langlands-group.pdf . Any comments? RobHar 23:35, 4 September 2007 (UTC)
