Mirosław Dudek (Institute of Physics, University of Zielona Góra) On Lotka-Volterra models of population growth.

Abstract: After a short review of the deterministic growth models which are used in modelling the population dynamics ([Wangersky]) we discuss how to model the growth of age-structured population with genetics ([Dudek]). In the latter case, a deterministic model of an age structured population has been constructed which shares many features common with the discrete time Penna model ([Penna],[Moss de Oliveira et al]) of genetic evolution. Similarly, as in the Penna model, genetic information is represented by the fraction of defective genes in the population under consideration. We discuss some extentions of the model ([Dudek]) including methods of self-adaptive stochastic processes.   References: 1. V.
