Title: The Force of Fluctuations: Analysis and Control of Exctinctions on Networks
Abstract: Noise in various forms is known to cause switching between states, create new meta-stable states, and form global dynamical structures. In this talk, I will review some previous work on the effects of noise in static and adaptive networks, and show how to extend the theory to heterogeneous networks with a specified degree distribution. Applications will be to epidemic spread and novel optimal network control in large populations.Specifically, we have developed new mathematical and computational techniques demonstrating that both highly connected individuals and those with a few connections should be targeted in specific proportions, using vaccination or treatment, in order to minimize mean extinction times. The optimal approach gives orders of magnitude improvement over known strategies.
