Abstract ::  After a brief description of what point vortices and passive particles are - on the plane and on the sphere - and how they can mimic real flows, we will derive their dynamic equations from the two-dimensional incompressible Euler equation. Next, we establish the connection between the relative equilibria of identical point (planar) vortices and the first and second derivatives of the polynomial that has the positions of the vortices as its roots. Finally, we will present some open problems, as well as simulations based on computational models.
