Hopf monoids and generalized permutahedra
Descripción general
Resumen del artículo
The paper introduces a Hopf algebraic structure on generalized permutahedra, proving they are the universal family of polytopes with this structure. It presents a cancellation-free antipode formula and demonstrates how this framework unifies classical results in combinatorics related to graphs, matroids, posets, and inversion of power series, offering potential for new discoveries.
