7). We wish to verify that Pnþ1 ; constructed from Eq. 7), and Pn satisfy Eq. 4). We shall also verify that the normalization factor, 2n þ 1; on the right hand side of Eq. 7) leads to the coefficient of the highest power in Pn being 1. Vortex Crystals 43 pffiffiffiffiffiffiffiffiffi We first use the result Eq. 6) with Q ¼ Pn21 ; P ¼ 2n þ 1 Pn ; and R ¼ Pnþ1 : By assumption Pn21 and Pn ; or equivalently Q and P, satisfy Tkachenko’s equation. Since Q, P and R satisfy Eq. 6), we conclude that P and R, or equivalently Pn and Pnþ1 ; satisfy Eq.

Aref et al. point vortices carry all the vorticity in the flow. If not, one has to remember the existence of a largely passive, uniform vorticity in the background. ) Using nb ¼ xb =R in the numerator, and lxa 2 xb l2 ¼ 2ðR2 2 xa ·xb Þ in the denominator, Eq. 1) may be recast as N xa £ xb dxa 21 X 0 ¼ G : 4pR b ¼ 1 b R2 2 xa ·xb dt ð10:2Þ Another interesting reformulation arises by projecting the surface of the sphere stereographically onto the plane tangent to the sphere at its north pole. 5) and the result is 2 3 N Gb dza ð1 þ lza l2 Þ2 4 X S za 5 0 ¼ 2 : ð10:3Þ dt z 2 zb 8piR2 1 þ lza l2 b¼1 a Here za is the complex position in the tangent plane of the projection of vortex a from the sphere, and S is again the sum of the vortex strengths [Eq.

One can often view the evolution of an N-vortex system as a succession of ‘visits’ to the vicinity of the unstable equilibria, where a degree of regularity both in the spatial pattern and the temporal evolution prevails. Between these ‘visits’ the motion evolves more rapidly and characteristic configurations are not in evidence. The exclusive focus on stable equilibria that has historically dominated the subject of vortex statics may, thus, be overly restrictive. As an intriguing case in point, Fig.
