Query: The triangulated Hopf category n_+SL(2)   We discuss an example of a triangulated Hopf category related to SL(2). It is
an equivariant derived category equipped with multiplication and
comultiplication functors and structure isomorphisms. We prove some coherence
equations for structure isomorphisms. In particular, the Hopf category is
monoidal.
