 "Bifurcations in cell cycle models"
 ABSTRACT: Cell proliferation is modeled via the regulation of 
its nuclear proteins.
The models in this study are that of systems of ordinary differential equations 
which are rich in nonlinear dynamics.  We will discuss the development of a
phase-specific mathematical model, comparison of its numerical simulations with
published experimental data and, few bifurcations found in the model.
