DESCRIPTION:Speakers: Sonia Boulal\n\nWe consider a Galton–Watson tree i
 n which each node is independently marked\, with a probability that depend
 s on its number of offspring.We give a complete picture of the local conve
 rgence of critical or subcritical marked Galton–Watson trees\, condition
 ed on having a large number of marks.In certain cases\, the limit is a ran
 domly marked tree with an infinite spine\, known as the marked Kesten tree
 . In other cases\, the local limit is a randomly marked tree with a node h
 aving infinitely many children. This corresponds to the so-called marked c
 ondensation phenomenon.\n\nhttps://indico.math.cnrs.fr/event/17133/
