Hello!

I have a few questions on Reshetikhin Turaev invariants.

By RT any ribbon category ${\mathcal C}$ yields an invariant of oriented, framed links labelled with objects of ${\mathcal C}$.

Is there a general way to build from this an invariant of *unframed*, oriented links? At least in the case where one considers finite-dimensional modules over ${\mathcal U}_q({\mathfrak g})$ for simple ${\mathfrak g}$?

Howe does this relate to the general construction of an invariant of oriented, unframed links from an *enhanced* R-matrix?

I hope this isn't too elementary, but I couldn't find a reference.

Thank you very much!
