“…In the planar case these configurations also give rise to relative equilibria-orbits in which each particle moves on a circle at a common angular speed. For the Newtonian three-body and four-body problems it is known that central configurations in dimensions one, two, and three are finite for positive masses (Euler 1767;Lagrange 1772;Moulton 1910;Hampton and Moeckel 2006). There is also a generic finiteness result for 'Dziobek configurations' which applies to the case we are studying (Moeckel 2001) since the dimension of our configurations is n − 2.…”

“…Our proof strategy will be the same as that of Hampton and Moeckel (2006), but where they use the theory of Bernstein (1975), Khovanskii (1977), and Kushnirenko (1976) we will use the language of tropical geometry. Our equations for central configurations (described in Sect.…”
