Andreas Kyprianou (University of Bath)
The Prolific Backbone of a Superdiffusion

Abstract

We complete a result originally due to Evans and O'Connell in 1994 which equates the law of a supercritical, super-diffusion with quadratic branching mechanism to that of the spatial tree of a particle branching particle diffusion "dressed" with immigrating subcritical superdiffusions. We give a direct pathwise construction allowing for a fully general branching mechanism. The key to our construction is the use of the Dynkin-Kuznetsov N-measures. This is based on joint work with Julien Berestycki and Antoni Murillo.
