We first recall some basic facts from the theory of discrete-time Markov chains arising from two types neutral and non-neutral evolution models of population genetics with constant size. We then define and analyse a version of such models whose fluctuating total population size is conserved on average only. In our model, the population of interest is seen as being embedded in a frame process which is a critical Galton-Watson process. In this context, we address problems such as extinction… 

Extinction scenarios in evolutionary processes: A Multinomial Wright-Fisher approach

We study a generalized discrete-time multi-type Wright-Fisher population process. The mean-field dynamics of the stochastic process is induced by a general replicator difference equation. We prove

Karlin–McGregor Mutational Occupancy Problem Revisited

The equilibrium species counts as a function of n,  p and the total mutation probability are studied before considering various asymptotic regimes on n, p and $$\nu .$$ν.

A new approach is developed which contains the models mentioned above and provides simpler expressions for the latent roots and a greater dependence between the birth events and death events can be permitted, and non-independent mutations treated.

Asymptotics of Symmetric Compound Poisson Population Models

It is shown that the asymptotic behaviour of symmetric compound Poisson models is mainly determined by the characteristic value θrφ′(r−), which forces the model to be in the domain of attraction of a discrete-time Dirac coalescent.
