Asymptotic behavior of a second-order swarm sphere model and its kinetic limit

Abstract: We study the asymptotic behavior of a second-order swarm model on the unit sphere in both particle and kinetic regimes for the identical cases. For the emergent behaviors of the particle model, we show that a solution to the particle system with identical oscillators always converge to the equilibrium by employing the gradient-like flow approach. Moreover, we establish the uniformin-time 2-stability using the complete aggregation estimate. By applying such uniform stability result, we can perform a rigorous me… Show more

“…In [6], the case of heterogeneous frequencies is investigated. In [20,26], the second-order high-dimensional Kuramoto model is discussed. In [12], based on the global order parameter, the d-dimensional Kuramoto model with positive feedback is considered.…”

“…The study of this model in physics is motivated by its relation to synchronization of quantum bits [8], [9], but it also appears in control systems designed to achieve reduced rigid-body attitude synchronization, i.e., to coordinate the pointing orientations of robots [6], [22], [23], in bio-inspired models of source-seeking and learning [12], [24], and in machine learning applications [13]. There are several variations of the model, including second-order dynamics [25], [26] and discrete-time maps [27]. A limitation in our current understanding of the Lohe model is the restriction to combinations of complete or acyclic networks [11], [14], [15], [23], [26], homogeneous frequencies [6], [10], [21], [25], and local behavior [10], [11], [25], [26], [28].…”

By contrast, this paper concerns the global behavior of the Lohe model with heterogeneous frequencies over non-trivial networks.…”
