Karlin-McGregor mutational occupancy problem revisited

Abstract

Some population is made of n individuals that can be of p possible species (or types). The update of the species abundance occupancies is from a Moran mutational model designed by Karlin and McGregor in 1967. We first study the equilibrium species counts as a function of n, p and the total mutation probability $\nu$ before considering various asymptotic regimes on n, p and $\nu$.
