Abstract
It is well known that the linear stability of elliptic Lagrangian solutions depends on the mass parameter β=27(m1m2+m2m3+m3m1)/(m1+m2+m3)2[0,9] and the eccentricity e[0,1). Based on new techniques for evaluating the hyperbolicity and the recently developed trace formula for Hamiltonian systems [9], we identify regions for (β,e) such that elliptic Lagrangian solutions are hyperbolic. Consequently, we have proven that the elliptic relative equilibrium of square central configurations is hyperbolic with any eccentricity.
