combinatorial Hopf algebra

Some Hopf algebras encode relevant combinatorial information and are quite common and useful in algebraic combinatorics? in general. More recently Hopf algebras appeared also in the study of renormalization of QFT, controlling its combinatorics. Combinatorial Hopf algebra may denote either informal notion of Hopf algebra coming from combinatorics (and, in particular, study of various rings of symmetric functions), but also, now standard notion as a pair of a Hopf algebra HH over kk equipped with a character ζ:Hk\zeta: H\to k, the zeta function of a Hopf algebra.


One of the original sources is:

  • S. A. Joni and Gian-Carlo Rota, Coalgebras and bialgebras in combinatorics, Umbral Calculus and Hopf Algebras (Norman, OK, 1978), Contemp. Math., vol. 6, AMS, Providence, RI, 1982.

There is also another early article from Rota:

  • Gian-Carlo Rota, Hopf algebra methods in combinatorics, Problèmes combinatoires et théorie des graphes (Colloq. Internat. CNRS, Univ. Orsay, Orsay, 1976), pp. 363–365, Colloq. Internat. CNRS 260, CNRS, Paris 1978.

(Despite the title, though, this is just a short note that mainly discusses applications of Rota’s theory to the so-called umbral calculus, without making the Hopf algebra structure explicit.)

For the basic intuition for Hopf algebras in combinatorics see the chapter 5 of S. Majid’s Foundation of quantum group theory. Nowadays the major book on combinatorial Hopf algebras is
