Arborified zeta values (AZVs) are a generalisation to trees of Multizeta values. They can be defined through the branching of the Euler-MacLaurin operator. We will review this construction without mentioning the analytical details, and focusing instead on the algebraic properties of AZVs. In particular, we will see that AZVs are morphisms for new shuffle-like products on trees.
