An approach to Hopf algebras via Frobenius coordinates II
Lars Kadison, A. A. Stolin
We study a Hopf algebra , which is finitely generated and projective over a commutative ring , as a -Frobenius algebra. We define modular functions in this setting, and pr…

An Approach to Hopf Algebras via Frobenius Coordinates I
Lars Kadison, A. A. Stolin
In Section 1 we introduce Frobenius coordinates in the general setting that includes Hopf subalgebras. In Sections 2 and 3 we review briefly the theories of Frobenius algebras and…
