Introduction:

Describing and predicting the behaviour of interacting social individuals in a group is a challenging task, since there is no obvious system of physical laws that should be obeyed. Various modelling approaches have been employed by researchers in the field: microscopic/ODE and macroscopic/PDE models, measure-valued formulations, cellular automata, local or nonlocal descriptions, kinetic formulations, etc. This session aims at bringing together various views on modelling these systems and their dynamics. Specific applications (bacteria, animals, people), as well models that incorporate universal features of aggregations, will be presented. |
