On the stability of the Lagrangian homographic solutions in a curved three-body problem on \(\mathbb{S}^2\). (English) Zbl 1263.70010
Summary: The problem of three bodies with equal masses in \(\mathbb{S}^2\) is known to have Lagrangian homographic orbits. We study the linear stability and also a “practical” (or effective) stability of these orbits on the unit sphere.
