Jan 5	comment	Prove well-definedness of comultiplication and counit of $GL_q(2)$ and $SL_q(2)$. certainly! google my name on here and you should find my contact info.
Jan 5	answered	$U_q$ Quantum group and the four variables: E, F, K, K^{-1}
Dec 28	comment	Prove well-definedness of comultiplication and counit of $GL_q(2)$ and $SL_q(2)$. I'm working through majid's "primer on quantum groups" (disclaimer: majid is my phd supervisor) along with kassel, and I have a few other texts handy, but they're harder for an undegrad to crack. feel free to email me about it, though.

Dec 17	comment	Prove well-definedness of comultiplication and counit of $GL_q(2)$ and $SL_q(2)$. a word of warning about kassel - it's a great book, but he tends to be a bit "over axiomatic" and it's a bit hard to see the forest through the trees sometimes. For instance, it's a lot easier to just compute $\Delta(\text{det_q})$ then to follow his chain of propositions. It helps to have a few other texts handy to cross-reference these things.
Dec 17	comment	Prove well-definedness of comultiplication and counit of $GL_q(2)$ and $SL_q(2)$. I re-wrote it a bit more coherently, also describing coideals a tad bit more and explaining how he gets the computation. You should ensure you have a good idea of ideals and quotient rings if you don't have that already. coideals were described in ch3. I'm a 2nd year phd student and I find this hopelessly confusing myself. regards!
Dec 17	revised	Prove well-definedness of comultiplication and counit of $GL_q(2)$ and $SL_q(2)$. same thing, but written more coherently.

Dec 17	comment	Prove well-definedness of comultiplication and counit of $GL_q(2)$ and $SL_q(2)$. do you understand how the bialgebra structure on $M_q(2)$ works?
Dec 17	comment	proving that a action of hopf algebra k(G) on A implies a G-grading on A I added some text for clarification, does that help?

Aug 6	accepted	What are some examples of vector spaces that aren't graded?
Aug 6	comment	What are some examples of vector spaces that aren't graded? well that certainly clears things up. thanks!
