"Equilibrium vortex configurations in domains with boundary"

Given a stable configuration of point vortices for steady two dimensional inviscid, incompressible fluid flow in a domain D it is shown that there is another stable configuration of stationary vortices in D with vortices near the original vortices plus additional vortices near any points on the boundary where the speed of the original flow is a non-zero relative minimum. Examples are given for several different flow configurations.
