Title: Analyzing dynamical systems through the concept of stochastic bifurcations

Time: Thu, Jan 20, 2011, 3pm

Place: bldg 14, room 3.02/03

Abstract:
The investigation of stochasticity is very important for the understanding of the dynamical features of real systems, since they are inevitably affected by internal and external noise sources. We study the influence of additive Gaussian white noise on different systems, including Duffing-Van der Pol oscillator, paradigmatic mathematical model of synthetic gene oscillator, synthetic gene relaxation oscillator and genetic networks. We find that their dynamics can be well characterized using the concept of stochastic bifurcation consisting in a qualitative change of the stationary probability distribution. Moreover, we show that this approach allows effective characterization of the dynamics of gene regulatory networks, as well.
