A MODEL FOR THE GROWTH OF A POPULATION EXHIBITING STAGE STRUCTURE - CANNIBALISM AND COOPERATION

[摘要] A model of a stage-structured population with fixed maturity time for the immature stage and interaction terms that may be interpreted as cooperation or cannibalism is proposed. The existence and stability of the equilibrium set are discussed. In the case of cannibalism, it is shown by a numerical example how a Hopf bifurcation could result in a stable periodic solution.
