On time-changes and profiles of trees

Gerónimo Uribe Bravo, Universidad Nacional Autónoma de México
Monday, February 28, 2022 - 2:30pm to 3:20pm
In this talk, we will discuss a scaling limit for the sequence
of generation sizes of a (rooted plane) tree with a given degree sequence. 
The main tools used in the proof include fluctuation theory and the
stability analysis of a time-change equation for exchangeable increment processes.  
The scaling limit result extends and (probabilistically) proves a
conjecture by Aldous concerning the profile of conditioned
Galton-Watson trees first settled by Drmota and Gittenberger using
analytic combinatorics.
