Cosemisimple pointed Hopf algebras
Assuming that we are speaking about finite dimensional hopf algebras, the answer is yes:
Since $H$ is cosemisimple if and only if $H\cong Corad(H)$ (as coalgebras) and $H$ is pointed if and only if $C …

The double cover in the classical limit of $U_q(\mathfrak{sl}_2)$
Well, i am not sure if this is what the OP is looking for but here is an heuristic method for computing the limit, avoiding the use of another algebra defined at $q=1$ and thus bypassing the "double c …

Symplectic orbits in projective Hilbert spaces are simply connected
I do not have access to the article you are citing but I have made a little search and I think the answer to your question is yes (given that we are speaking about a non-compact, connected, semisimple …
