ON SCALING LIMITS OF MARKOV BRANCHING TREES


Abstract:
Probabilists and combinatorists are interested since a long
time in the asymptotic description of large random trees, as, 
for example, large uniform trees (chosen uniformly at random 
in a certain class of trees) or large conditioned Galton-Watson 
trees. After recalling classical results on that topic, we will 
develop the case of a family of random trees satisfying a 
Markov branching property. Roughly, this property says that 
the subtrees above some given height are independent with 
a law that depends only on their total size, the latter being 
either the number of leaves or vertices. Applications to the 
description of scaling limits of (1) random uniform unordered 
trees, (2) growing trees built recursively, (3) Galton-Watson 
trees will then be discussed.

This talk is based on joint works with Gregory Miermont, 
Jim Pitman and Matthias Winkel.



Tutti gli interessati sono invitati a partecipare.

Il seminario e' organizzato dalla "de Castro" Statistics Initiative
(http://www.carloalberto.org/stats) in collaborazione con il 
Collegio Carlo Alberto.
