报告摘要：We study the scaling behaviour of the extinction time of the simple logistic birth and death process, as the carrying capacity n tends to 1, when the reproductive rate r and the initial value X0 are allowed to vary arbitrarily with n. We give a complete description of all possible rescaled limit distributions, and give the precise scaling in each case. In particular, the change in behaviour from small to large initial values, and from small to large reproductive rate as the system passes through its phase transition window, are clearly exhibited.
