A generalized two-sex logistic model.
We provide a generalization of the logistic two-sex model with ephemeral pair-bonds and with stable couples without assuming any specific mathematical form for fertility, mortality and the mating function. In particular, we establish a necessary and sufficient condition on the fertility/mortality density-dependent ratio that ensures the existence of the logistic behaviour. Several differences a...
متن کاملA note on 'A generalized two-sex logistic model'.
We re-visit the recently published paper on a generalization of the two-sex logistic model by Maxin and Sega [A generalized two-sex logistic model, J. Biol. Dyn. 7(1) (2013), pp. 302-318]. We show that the logistic assumption of a non-increasing birth rate can be replaced by a more general assumption of a non-increasing ratio between the female/male birth and mortality rate. In this note we ind...
متن کاملThe logistic, two-sex, age-structured population model.
In this paper, we introduce the logistic effect into the two-sex population model introduced by Hoppensteadt. We address the problem of existence and uniqueness of continuous and classical solutions. We first give sufficient conditions for a unique continuous solution to exist locally and also globally. Next, the existence of classical solutions is established under some mild assumptions on the...
متن کاملA generalized logistic distribution
for −∞ < z < ∞. The properties of this distribution and its generalizations have been studied by several authors. Of particular eminence are the numerous papers on this topic by Professor N. Balakrishnan and his colleagues; see, for example, Balakrishnan [1, 2, 3], Balakrishnan and Aggarwala [4], Balakrishnan et al. [5, 7, 12], Balakrishnan and Chan [6], Balakrishnan and Joshi [8], Balakrishnan...
متن کاملNoise-induced transitions in a generalized logistic model with delay
The stochastic phenomena in the generalized randomly forced logistic model with delay is considered. The probabilistic mechanisms of the noise-induced transitions between coexisting attractors, and between separate parts of the unique attractor are studied. For the analysis of these phenomena, a new semi-analytical approach is suggested. Our method takes into account a geometry of the mutual ar...
