Event details
In this talk I explore how stochastic effects in finite size populations can lead to qualitatively different dynamics from that predicted by deterministic descriptions of the same system. Specifically I will look at the phenomenon of stochastic resonance, following closely the original paper on the subject, concerning a predator-prey model. In the last 5 years many more papers (~10) have used similar analysis to uncover the same phenomenon in a variety of different biological and chemical systems.
