Local and global rigidity for isometric actions of simple Lie groups on pseudo-Riemannian manifolds
Raul Quiroga-Barranco
Let be a finite volume analytic pseudo-Riemannian manifold that admits an isometric -action with a dense orbit, where is a connected non-compact simple Lie group. For lo…
Rigidity of an Isometric -Action
Raul Quiroga-Barranco, Eli Roblero-Méndez
We characterize the universal covering of connected analytic pseudo-Riemannian manifolds which admit a non-trivial and isometric action of the simple Lie group w…
On low-dimensional manifolds with isometric -actions
Gestur Ólafsson, Raul Quiroga-Barranco
Denote by the universal covering group of , the linear group of isometries of the pseudo-Hermitian space of signat…
Isometric actions of simple Lie groups on pseudoRiemannian manifolds
Raul Quiroga-Barranco
Let M be a connected compact pseudoRiemannian manifold acted upon topologically transitively and isometrically by a connected noncompact simple Lie group G. If m_0, n_0 are the dim…
