It's just one of those terms that always confuses me (algebras have more structures than rings, but Hopf rings have more structures than Hopf algebras). Did you trace through Macdonald's "Symmetric functions and Hall polynomials"? I think something of what you need must be contained in the relevant chapter there. | |

| Mar 7, 2012 at 19:27 | comment | added | Joe Johnson | @VladimirDotsenko: Having a product and coproduct makes it a hopf algebra. A hopf ring has an additional product that satisfies some further axioms with the coproduct and original product. | |
