This paper presents a review and critical analysis on the modeling of the dynamics of
vehicular traffic, human crowds and swarms seen as living and, hence, complex systems. It …

Emergent dynamics of the Cucker–Smale flocking model and its variants

YP Choi, SY Ha, Z Li - Active Particles, Volume 1: Advances in Theory …, 2017 - Springer
In this chapter, we present the Cucker–Smale-type flocking models and discuss their
mathematical structures and flocking theorems in terms of coupling strength, interaction …

A rigorous derivation from the kinetic Cucker–Smale model to the pressureless Euler system with nonlocal alignment

A Figalli, MJ Kang - Analysis & PDE, 2018 - msp.org
We consider the kinetic Cucker–Smale model with local alignment as a mesoscopic
description for the flocking dynamics. The local alignment was first proposed by Karper …

[图书][B] Dynamics and analysis of alignment models of collective behavior

R Shvydkoy - 2021 - Springer
Collective phenomena occur in nature, technology, and social behavior in a vast variety of

[PDF][PDF] Uniform stability of the Cucker-Smale model and its application to the mean-field limit

SY Ha, J Kim, X Zhang - Kinet. Relat. Models, 2018 - pdfs.semanticscholar.org
1. Introduction. Collective behaviors of many-body systems are ubiquitous in the ensemble
of self-propelled particles, eg, flocking of birds, herding of sheep, and synchronicity of …

Emergent behaviors of thermodynamic Cucker--Smale particles

SY Ha, J Kim, T Ruggeri - SIAM journal on mathematical analysis, 2018 - SIAM
We study the flocking dynamics of a generalized Cucker--Smale (CS) model for
thermodynamic particles. The original CS model deals with flocking dynamics of mechanical …

Singular cucker–smale dynamics

We present a uniform-in-time stability and uniform mean-field limit of a thermodynamic
Cucker-Smale model with small diffusion velocityf (for short, the SDV-TCS model). The …

[HTML][HTML] Emergent dynamics of Cucker–Smale flocking particles in a random environment

SY Ha, J Jeong, SE Noh, Q Xiao, X Zhang - Journal of Differential …, 2017 - Elsevier
We present a new kinetic Cucker–Smale–Fokker–Planck (CS-FP) type equation with a
degenerate diffusion, which describes the dynamics for an ensemble of infinitely many …

Asymptotic analysis of Vlasov-type equations under strong local alignment regime

MJ Kang, AF Vasseur - … Models and Methods in Applied Sciences, 2015 - World Scientific
We consider the hydrodynamic limit of a collisionless and non-diffusive kinetic equation
under strong local alignment regime. The local alignment is first considered by Karper …
