Limit of trees with fixed degree sequence

Résumé

We use a new stick-breaking construction, also introduced independently by Addario-Berry, Donderwinkel, Maazoun, and Martin in arXiv:2107.09726, to study uniform rooted trees with fixed degree sequence D (D-trees). This construction allows us to prove, under natural conditions of convergence of the degree sequence, that D-trees converge toward either P-trees or ICRT. Alongside we provide an upper-bound for the height of D-trees. We deduce similar results concerning P-trees and ICRT. In passing we confirm a conjecture of Aldous, Miermont, and Pitman arXiv:math/0401115 stating that Lévy trees are ICRT with random parameters.
