Dual random fragmentation and coagulation and an application to the genealogy of Yule processes

Jean Bertoin, Christina Goldschmidt

Published 2004-08-10Version 1

The purpose of this work is to describe a duality between a fragmentation associated to certain Dirichlet distributions and a natural random coagulation. The dual fragmentation and coalescent chains arising in this setting appear in the description of the genealogy of Yule processes.
