Talk:Quasitriangular Hopf algebra

There is a confusion between two kinds of $\phi$. However I do not know how to correct it due to the following :

$\phi$

$\phi \otimes$

(see the wiki code to understand what confuse me). The one seems to be html while the other looks like LaTeX. How to force LaTeX everywhere ?

If anybody knows where these were first defined can they put that in the article? I believe they are attributed to both Drinfeld and Jimbo, but I do not know which articles. —Preceding unsigned comment added by 137.111.90.68 (talk) 04:11, 24 November 2007 (UTC)

I think it is also nice to say that the categories of representations of a quasitriangular Hopf algebra is braided. (Quasitriangular Hopf algebras are also called braided Hopf algebras for this reason.) —Preceding unsigned comment added by 130.54.16.83 (talk) 06:41, 24 February 2009 (UTC)
