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 $1$, 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 This survey article introduces readers to the recent results of the author, also unpublished, showing an application of the fixed point theory.", "revisions": [ { "version": "v1", "updated": "2020-07-03T15:00:45.000Z" } ], "analyses": { "keywords": [ "inverse problem", "central configurations play", "collinear configuration central", "important role", "body problem" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
