(April 23, 2004 2:00 PM - 5:00 PM)
Specifcally, the talk will include: 1) Formulation and stability analysis of the variable yield model; 2) A subcritical bifurcation lemma, divergence criterion; 3) Several examples involving the divergence criterion; and 4) Examples of complicated dynamics for two competitors, period-doubling cascades, Neimark-Sacker bifurcation.
