     Dynamical Systems with Time-scale Interference for 
     a Theory of Biological Plasticity and Robustness

Biological dynamical systems both have plasticity to adapt 
novel environments and robustness to keep their internal 
state. I will discuss dynamical-systems approaches to deal 
with the plasticity and robustness, stressing the importance 
of interference between modes with distinct time scales. The 
topics will cover.
(i) Autonomous regulation of time scales by enzyme-limited 
competition, leading to epigenetic memory and biological 
homeostasis.
(ii) Autonomous switching of quasistationary state in 
dynamical systems consisting of slow and fast variables 
(iii) Self-consistent bifurcation in coupled dynamical 
systems resulting in cell differentiation from a stem cell
