Web9 de set. de 2024 · In systems of \(n\ge 4\) inviscid vortices, it is known that, generically, the movement of test particles within the flow is chaotic. However, point vortices create regions of stability around them; i.e., while they move chaotically within the fluid, the movement of particles within those regions of stability is predictable with respect to the vortex center [].
