The Global Phase Space of the Three-Vortex Interaction System
We derive a symplectic reduction of the evolution equations for a system of three point vortices and use the reduced system to succinctly explain a kind of bifurcation diagram that has appeared in the literature in a form that was difficult to understand and interpret. The reduction proceeds in two steps: a reduction to Jacobi coordinates and a Lie-Poisson reduction.
