As a by-product, the large deviations for Zn+1/Zn are also studied. We can see that there is a phase transition in converging rates depending on the generating functions of both branching and immigration.展开更多

文摘We study the convergence rates of the harmonic moments for supercritical branching processes with immigration Zn, extending the previous results for non-immigration cases in literature. As a by-product, the large deviations for Zn+1/Zn are also studied.
