We study a hydrodynamic Cucker-Smale-type model with time delay in communication and information processing, in which agents interact with each other through normalized communication weights. The model consists of a pressureless Euler system with time delayed non-local alignment forces. We resort to its Lagrangian formulation and prove the existence of its global in time classical solutions. Moreover, we derive a sufficient condition for the asymptotic flocking behavior of the solutions… 
Exponential asymptotic flocking in the Cucker-Smale model with distributed reaction delays.
Using backward-forward and stability estimates on the quadratic velocity fluctuations, sufficient conditions are derived for asymptotic flocking of the solutions of the Cucker-Smale system and the applicability of the theory to particular delay distributions is demonstrated.
Cucker-Smale model with finite speed of information propagation: well-posedness, flocking and mean-field limit
We study a variant of the Cucker-Smale model where information between agents propagates with a finite speed c > 0. This leads to a system of functional differential equations with state-dependent

The delayed Cucker-Smale model with short range communication weights
A simple sufficient condition of the initial data to the non-flocking behavior of the delayed Cucker-Smale model is established and a flocking result is obtained, which also depends upon theinitial data in the short range communication case.

We study a Cucker-Smale-type system with time delay in which agents interact with each other through normalized communication weights. We construct a Lyapunov functional for the system and provide
Emergent Dynamics for the Hydrodynamic Cucker-Smale System in a Moving Domain
The initial value problem with a moving domain is considered to investigate the global existence and time-asymptotic behavior of classical solutions, provided that the initial mass density has bounded support and the initial data are in an appropriate Sobolev space.
A Cucker-Smale Model with Noise and Delay
Sufficient conditions for flocking for the generalized Cucker--Smale model are derived by using a suitable Lyapunov functional and a new result regarding the asymptotic behavior of delayed geometric Brownian motion is obtained.

It is shown that there exist critical thresholds in the phase space of the initial configuration which dictate the global regularity versus a finite-time blow-up, and the regularity of non-local alignment in the presence of vacuum is explored.
A Review on Attractive–Repulsive Hydrodynamics for Consensus in Collective Behavior

Pressureless Euler alignment system with control
The control dynamics is characterized as a sub-optimal approximation to the optimal control problem constrained to the evolution of the pressureless Euler alignment system and the critical thresholds that lead to global regularity or finite-time blow-up of strong solutions in one and two dimensions are discussed.
Emergent dynamics of the Cucker-Smale flocking model and its variants

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
