A bijection between shrubs and series-parallel posetsArticle

Authors: Frédéric Chapoton ORCID1

Motivated by the theory of operads, we introduce new combinatorial objects, called shrubs, that generalize forests of rooted trees. We show that the species of shrubs is isomorphic to the species of series-parallel posets.
