Standing waves of fixed period for $n+1$ vortex filaments

Analysis of PDEs 2019-03-21 v1

Abstract

The n+1n+1 vortex filament problem has explicit solutions consisting of nn parallel filaments of equal circulation in the form of nested polygons uniformly rotating around a central filament which has circulation of opposite sign. We show that when the relation between temporal and spatial periods is fixed at certain rational numbers, these configurations have an infinite number of homographic time dependent standing wave patterns that bifurcate from these uniformly rotating central configurations.
