Abstract

In this paper, we generalize the Cucker–Smale model under a general digraph on the infinite cylinder with the help of the Lie group structure of the infinite cylinder and study the flocking behavior of this model. We show that for $0 \leq \beta \lt 1 / (2h)$ unconditional flocking occurs, where h is the shortest height of the spanning trees of the digraph, and conditional flocking occurs for $\beta \geq 1 / (2h)$ under some conditions depending only on the initial data.
