The scenario takes into account the presence of~multiple time-varying communication delays.},

	abstract = {We consider a second order non-linear consensus (flocking) network of a finite population of autonomous agents and~prove that the long-term behavior of its solution is towards a common value while the flock remains connected. We elevate the~analysis to a collision avoidance type flocking after taking into consideration repelling forces between agents.},

	abstract = {We revisit the linear distributed consensus problem~in continuous time, to provide a simple and elegant proof~under very mild assumptions. Our approach is based on a novel~extension of the contraction coefficient that can be adapted to~the continuous time version of the model. We apply our results~in non-linear second order consensus networks of Cucker-Smale type and we obtain new initial conditions for asymptotic~flocking.},

We show that our method unifies a number of proposed models in the literature as well as it extends and generalizes existing results.},

We provide conditions for convergence of to a common constant value, under an increased~connectivity condition. The results are delay-independent in the sense that they hold for~arbitrary bounded delays. Our approach makes use of fundamental concepts from the Non-Negative Matrix Theory in a fairly elementary way.},

We provide sufficient conditions for convergence to a common consensus point, by means of a stability in variation argument and fixed point theory. Our approach provides both an estimation on the rate of convergence and an implicit expression for the consensus point.},
