Journal of Lie Theory 27 (2017), No. 4, 1179--1197 Copyright Heldermann Verlag 2017 Rigidity of an Isometric SL(3,R)-Action Raúl Quiroga-Barranco CIMAT, Apartado Postal 402, Guanajuato 36250, Mexico quiroga@cimat.mx Eli Roblero-Méndez Universidad Autónoma de Chiapas, Carretera Emiliano Zapata Km 8, Tuxtla Gutierrez 29050, Chiapas -- Mexico elirm@cimat.mx We describe the universal covering space of a finite volume connected analytic pseudo-Riemannian manifold M with dimension at most 14 that admits a non-trivial isometric analytic action of the simple Lie group SL(3,R) with a dense orbit. If such a manifold is also weakly irreducible we prove that M-tilde is isometric to, or a quotient space of a simple Lie group containing SL(3,R). Keywords: Simple Lie groups, pseudo-Riemannian manifolds, rigidity results. MSC: 22F50, 53C24, 53C50 [ Fulltext-pdf (315 KB)] for subscribers only. |
