Are Orthogonal Separable Coordinates Really Classified?
We prove that the set of orthogonal separable coordinates on an arbitrary (pseudo-)Riemannian manifold carries a natural structure of a projective variety, equipped with an action of the isometry group. This leads us to propose a new, algebraic geometric approach to the classification of orthogonal...

| description | We prove that the set of orthogonal separable coordinates on an arbitrary (pseudo-)Riemannian manifold carries a natural structure of a projective variety, equipped with an action of the isometry group. This leads us to propose a new, algebraic geometric approach to the classification of orthogonal separable coordinates by studying the structure of this variety. We give an example where this approach reveals unexpected structure in the well known classification and pose a number of problems arising naturally in this context.

 of Sergio Benenti. The full collection is available at http://www.emis.de/journals/SIGMA/Benenti.html.
 This notice is based on a talk held at the workshop “Analytical Mechanics and Dif ferential
 Geometry” at the Universit`a di Torino on 12th and 13th March 2015 on the occasion of Sergio
 Benenti’s 70th birthday. The author would like to thank the organisers, Claudia Chanu and
 Giovanni Rastelli, for their kind invitation and hospitality, as well as Willard Miller for valuable
 discussions on the subject. en Інститут математики НАН України Symmetry, Integrability and Geometry: Methods and Applications Are Orthogonal Separable Coordinates Really Classified? Article published earlier |
