Algebraic and combinatorial structures on pairs of twin binary trees
Samuele Giraudo
We give a new construction of a Hopf algebra defined first by Reading whose bases are indexed by objects belonging to the Baxter combinatorial family (i.e., Baxter permutations, pa…

Balanced binary trees in the Tamari lattice
Samuele Giraudo
We show that the set of balanced binary trees is closed by interval in the Tamari lattice. We establish that the intervals [T0, T1] where T0 and T1 are balanced trees are isomorphi…
