General branching processes in discrete time as random trees
Peter Jagers, Serik Sagitov
The simple Galton--Watson process describes populations where individuals live one season and are then replaced by a random number of children. It can also be viewed as a way of ge…
The mixing advantage is less than 2
Kais Hamza, Peter Jagers, Aidan Sudbury +1
Corresponding to independent non-negative random variables , are values , where each is the expected value of the maximum of independent cop…
Supercritical general branching processes conditioned on extinction are subcritical
Peter Jagers, Andreas Nordvall Lagerås
It is well known that a simple, supercritical Bienaymé-Galton-Watson process turns into a subcritical such process, if conditioned to die out. We prove that the corresponding holds…
The coalescent effective size of age-structured populations
Serik Sagitov, Peter Jagers
We establish convergence to the Kingman coalescent for a class of age-structured population models with time-constant population size. Time is discrete with unit called a year. Off…
