| Aug 18, 2010 at 18:32 | comment | added | David Jordan | John, To my mind, co-quasitriangular Hopf algebras and quasitriangular Hopf algebras are essentially equivalent notions (the only real difference is that co-modules are automatically locally finite, whereas modules need to be explicitly declared as such for $R$-matrix to converge in many common examples). In particular, any statement about the former is just the adjoint of the latter. So looking at Proposition 2 in Chapter 8, where the analogous statement is proven for $R$-matrices, will show you the proof for $r$-forms. It looks like you will do some trick with writing $r=r\cdot 1$. | |
