comment Experimental evidence for non-abelian anyons?
"We stress that the presence of such a period is indicative of a non-Abelian nature of the ν = 5/2 state." Just an indication it seems...

David, were you able to take a look onto the problem?

Well, that could be, if you need a physical intuition. It is constrained to live on $S^2$.

Thanks, but arent there also other candidate systems proposed? Could you also provide links for them, please?

comment Experimental evidence for non-abelian anyons?
Both please! Theoretical description of candidate systems and whether experimental progress has been made.

comment Braiding statistics of anyons from a Non-Abelian Chern-Simon theory
Thank you!!! Well right on the first page of hep-th/9410091v2 it says that the formula you gave above is the one for the spherical case. So where is the difference to the plane?

Does the Knizhnik-Zamolodchikov equation also hold for other surfaces? Like the torus or the sphere?

comment Vector potential $A$ on a 2-sphere $S^2$ of radius $R$ with some points removed
Thank you David for the quick an elaborate reply! However, I am a little confused, as it seems to me, that you consider the case, where one removes a point at the origin of the unit ball. I am looking for the case where I take out e.g. three points on the hull of the unit ball, so $S^2-\{x_1,...,x_3\}$. Or am I wrong?

thank you. maybe then it is better to ask for the physical motivation of the connection field $A$ and what physically its colouring by $su(2)$ means?

comment What are the details of the renormalization of Chern-Simons theory?
The question is certainly not for beginners but I asked for a discussion of the concrete case of CS-theory. What are the properties of the $\beta$-function and why not any different?
