In this paper, we study the macroscopic behavior of the inertial spin (IS) model. This model has been recently proposed to describe the collective dynamics of flocks of birds, and its main feature is the presence of an auxiliary dynamical variable, a sort of internal spin, which conveys the interaction among the birds with the effect of better describing the turning of flocks. After discussing the geometrical and mechanical properties of the IS model, we show that, in the case of constant… 



Flocking Dynamics of the Inertial Spin Model with a Multiplicative Communication Weight

This paper presents several sufficient frameworks leading to the asymptotic mono-cluster flocking, in which spins and relative velocities tend to zero asymPTotically, in the deterministic inertial spin model.

A non-linear kinetic model of self-propelled particles with multiple equilibria

We introduce and analyse a continuum model for an interacting particle system of Vicsek type. The model is given by a non-linear kinetic partial differential equation (PDE) describing the

A well-posedness theory in measures for some kinetic models of collective motion

We present existence, uniqueness and continuous dependence results for some kinetic equations motivated by models for the collective behavior of large groups of individuals. Models of this kind have

Dynamics in a Kinetic Model of Oriented Particles with Phase Transition

A rigorous prove of convergence of the solution to a steady-state as time goes to infinity is given, and it is shown that in the supercritical case, the only initial conditions leading to the uniform distribution in large time are those with vanishing momentum.

Flocking and Turning: a New Model for Self-organized Collective Motion

This work proposes novel dynamical equations for the collective motion of polarized animal groups that account for correlated turning including solely social forces and derives a new model of collective motion based on a generalized coordinates of motion akin to a Hamiltonian formulation for rotations.

A New Model for Self-organized Dynamics and Its Flocking Behavior

We introduce a model for self-organized dynamics which, we argue, addresses several drawbacks of the celebrated Cucker-Smale (C-S) model. The proposed model does not only take into account the

Swarming Patterns in a Two-Dimensional Kinematic Model for Biological Groups

A continuum model for the motion of biological organisms experiencing social interactions and study its pattern-forming behavior, which takes the form of a conservation law in two spatial dimensions.

The derivation of swarming models: Mean-field limit and Wasserstein distances

A summary of the kinetic models derived as continuum versions of second order models for swarming, focusing on the question of passing from the discrete to the continuum model in the Dobrushin framework, gives qualitative bounds on the approximation of initial data by particles to obtain the mean-field limit of large ensembles of interacting particles.
