Clustering Analysis of Periodic Point Vortices with the Function
arXiv:physics/0608266 · doi:10.1143/JPSJ.76.043401
Abstract
A motion of point vortices with periodic boundary conditions is studied by using Weierstrass zeta functions. Scattering and recoupling of a vortex pair by a third vortex becomes remarkable when the vortex density is large. Clustering of vortices with various initial conditions is quantitated by the function used in point process theory in spatial ecology. It is shown that clustering persists if it is initially clustered like an infinite row or a checkered pattern.
