Hopf algebras with trace and representations
C. DeConcini, C. Procesi, N. Reshetikhin +1
We study the restriction of representations of Cayley-Hamilton algebras to subalgebras. This theory is applied to determine tensor products and branching rules for representations…

Hopf quivers
Claude Cibils, Marc Rosso
We classify graded Hopf algebras structures over path coalgebras, that is over free pointed coalgebras, using Hopf quivers which are analogous to Cayley graphs. The description inv…
