J. Bertoin et Jf. Le Gall, The Bolthausen-Sznitman coalescent and the genealogy of continuous-state branching processes, PROB TH REL, 117(2), 2000, pp. 249-266
We use Bochner's subordination to give a representation of the genealogical
structure associated with general continuous-state branching processes. We
then apply this representation to connections between a branching process
introduced by Neveu, and the coalescent process recently investigated by Bo
lthausen-Sznitman and others.
