New examples of indefinite hyper-Kaehler symmetric spaces
Ines Kath, Martin Olbrich
Following the approach to pseudo-Riemannian symmetric spaces developed in math.DG/0408249 we exhibit examples of indefinite hyper-Kaehler symmetric spaces with non-abelian holonomy…
On quantum ergodicity for vector bundles
Ulrich Bunke, Martin Olbrich
In the present paper we develop a framework in which questions of quantum ergodicity for operators acting on sections of hermitian vector bundles over Riemannian manifolds can be s…
On the structure of pseudo-Riemannian symmetric spaces
Ines Kath, Martin Olbrich
Following our approach to metric Lie algebras developed in math.DG/0312243 we propose a way of understanding pseudo-Riemannian symmetric spaces which are not semi-simple. We introd…
Metric Lie algebras and quadratic extensions
Ines Kath, Martin Olbrich
The present paper contains a systematic study of the structure of metric Lie algebras, i.e., finite-dimensional real Lie algebras equipped with a non-degenerate invariant symmetric…
