Fixed points and the inverse problem for central configurations

Dynamical Systems 2020-07-06 v1

Abstract

Central configurations play an important role in the dynamics of the nn-body problem: they occur as relative equilibria and as asymptotic configurations in colliding trajectories. We illustrate how they can be found as projective fixed points of self-maps defined on the shape space, and some results on the inverse problem in dimension 11, i.e. finding (positive or real) masses which make a given collinear configuration central. This survey article introduces readers to the recent results of the author, also unpublished, showing an application of the fixed point theory.
