Hopf Monoids in Varieties
We show that entropic varieties provide the canonical setting for a generaliziation of Hopf algebra theory. In particular we show that all naturally occurring functors in this context have the expected adjoints, when generalized to this level. In particular, universal measuring comonoids exist over every entropic variety, as do generalized group algebras, and these carry a canonical Hopf struct...
متن کاملSupercharacters and Hopf Monoids
Before the workshop, we suggested that the following reading list [1, 2, 3, 4, 5, 6] would be a good refreshment for all of us. At the start of the workshop, we identified the following problems that were worth considering given the recent progress in the area. 1. Higman’s conjecture. 2. Compute the antipode of the monoid scf(U) in the supercharacter basis. 3. Explicitly describe the multiplica...
متن کاملNOTES ON REGULAR MULTIPLIER HOPF ALGEBRAS
In this paper, we associate canonically a precyclic mod- ule to a regular multiplier Hopf algebra endowed with a group-like projection and a modular pair in involution satisfying certain con- dition
متن کاملLagrange’s Theorem for Hopf Monoids in Species
Following Radford’s proof of Lagrange’s theorem for pointed Hopf algebras, we prove Lagrange’s theorem for Hopf monoids in the category of connected species. As a corollary, we obtain necessary conditions for a given subspecies k of a Hopf monoid h to be a Hopf submonoid: the quotient of any one of the generating series of h by the corresponding generating series of k must have nonnegative coef...
متن کاملOn the cyclic Homology of multiplier Hopf algebras
In this paper, we will study the theory of cyclic homology for regular multiplier Hopf algebras. We associate a cyclic module to a triple $(mathcal{R},mathcal{H},mathcal{X})$ consisting of a regular multiplier Hopf algebra $mathcal{H}$, a left $mathcal{H}$-comodule algebra $mathcal{R}$, and a unital left $mathcal{H}$-module $mathcal{X}$ which is also a unital algebra. First, we construct a para...
