Coalgebras, Hopf Algebras and Combinatorics
In loving memory of my mother " A mathematician is a machine for converting coffee into theorems. " —Alfréd Rényi " A comathematician, by categorical duality, is a machine for converting cotheorems into ffee. " —anonymous Preface Hopf algebras are a relatively new concept in algebra, first encountered by their namesake Heinz Hopf in 1941 in the field of algebraic topology. In the 1960s, study o...
متن کاملTrace Semantics for Coalgebras
Traditionally, traces are the sequences of labels associated with paths in transition systems X → P(A×X). Here we describe traces more generally, for coalgebras of the form X → P(F (X)), where F is a polynomial functor. The main result states that F ’s final coalgebra Z ∼= −→ F (Z) gives rise to a weakly final coalgebra with state space P(Z), in a suitable category of coalgebras. Weak finality ...
متن کاملCyclic Homology of Hopf Comodule Algebras and Hopf Module Coalgebras
In this paper we construct a cylindrical module A♮H for an Hcomodule algebra A, where the antipode of the Hopf algebra H is bijective. We show that the cyclic module associated to the diagonal of A♮H is isomorphic with the cyclic module of the crossed product algebra A ⋊H. This enables us to derive a spectral sequence for the cyclic homology of the crossed product algebra. We also construct a c...
متن کاملHopf-Algebras and Coalgebras in ∞-Categories
The idea of the following is to suggest an ∞-categorical framework within which the ideas of coalgebras and Hopf-algebras (for various degrees of commutativity and cocommutativity) are natural and easy to define. These foundations will be used to describe interesting examples arising in chromatic homotopy theory and elsewhere in forthcoming work (especially with respect to Thom spectra). Sectio...
متن کاملForms of Coalgebras and Hopf Algebras
We study forms of coalgebras and Hopf algebras (i.e. coalgebras and Hopf algebras which are isomorphic after a suitable extension of the base field). We classify all forms of grouplike coalgebras according to the structure of their simple subcoalgebras. For Hopf algebras, given a W ∗-Galois field extension K ⊆ L for W a finite-dimensional semisimple Hopf algebra and a K-Hopf algebra H, we show ...
