title: Equilibria for the relative motion of three heavy spheres in Stokes fluid flow.
abstract: Dynamics of three identical solid spheres falling under gravity in low-Reynolds-number fluid flow is investigated. Stationary solutions are found. Their stability is discussed. Phase portraits for two types of symmetric motions are calculated.
