Several models are written as systems of ordinary differential equations with discontinuous right-hand side: this is a direct consequence of restricting interactions to a bounded region with non-vanishing strength at the boundary.

The state space determines the types of equilibrium that can be reached by the system. In this paper, we introduce the concept of Developmental Partial Differential flocking, i.e. Growth is thus determined by the distribution of such signal. The free evolution of such systems can tend to the formation of patterns, such as consensus or clustering, depending on the properties and intensity of the interaction forces between agents.

Bongini, M. Fornasier, F. Rossi, F. Solombrino, Mean-Field Pontryagin Maximum Principle,submitted,arXiv:1504.02236. We formulate this first-order optimality condition using the formalism of subdifferential calculus in Wasserstein spaces. In particular, we consider the Cauchy problem for a transport equation, where the velocity field depends on the measure itself. This model allows the transition from followers to leaders and vice versa, with scalar-valued transition rates depending nonlinearly on the global state of the system at each time.

Bounded-confidence models in social dynamics describe multi-agent systems, where each individual interacts only locally with others. The examples we have in mind span both cases of real dynamics, such as crowd in motion, but also virtual dynamics, such as opinion formation in social networks.
