Multiple Parameter Bifurcations in Ecological and Epidemiological Models
Dalhousie University, Halifax and
March 22, 2002
In this talk we will see that many biological systems such as predator-prey models with constant harvesting, epidemiological models with nonlinear incidence rate, predator-prey models with nonmonotonic functional response, etc. exhibit codimension two bifurcations which include Hopf, saddle-node, and homoclinic bifurcations. Examples of codimension three bifurcations will also be given.
