Sagitov, Serik et Jagers, Peter, The coalescent effective size of age-structured populations, Annals of applied probability , 15(3), 2005, pp. 1778-1797
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. Offspring numbers in a year may depend on mother.s age.
