Stability analysis of rings for 2nd order models in swarming

In this work we consider second order models in swarming in which individuals interact pairwise with a power-law repulsive-attractive potential. We study the stability for flock and mill ring solutions and we show how the stability of these solutions is related to the stability of a first order model. In unstable situations it is also possible to observe formation of clusters and fat rings.
