The role of noise in spreading processes
Research report (imported) 2012 - Max Planck Institute for Dynamics and Self-Organization
Spreading processes occur in many complex systems. They play an important role, for instance, in the formation of epidemics and the spread of evolutionary novelties. Until recently, most theories of those processes ignored or approximated the role of noise. The example of evolution illustrates, however, that random chance effects should not be neglected. We report a substantial advance in the analysis of these and more complex models.
