Ibrahima Drame
We code Galton-Walton trees by a continuous height process, in order to give a precise meaning to the convergence of forests of trees. This allows us to establish the convergence o…

Convergence to a Continuous State Branching Process with jumps and Height Process
Ibrahima Drame, Etienne Pardoux
In this work, we study asymptotics of the genealogy of Galton-Watson processes. Thus we consider a offspring distribution such that the rescaled Galton-Watson processes converges t…
