Lorentzian symmetric spaces which are Einstein-Yang-Mills with respect to invariant metric connections

Marco Castrillón López, Pedro M. Gadea, Eugenia Rosado Maria

We classify four-dimensional connected simply-connected indecomposable Lorentzian symmetric spaces $M$ with connected nontrivial isotropy group furnishing solutions of the Einstein…

Lifting diffeomorphisms to vector bundles

Jaime Muñoz Masqué, Eugenia Rosado María, Ignacio Sánchez Rodríguez

Criteria for a diffeomorphism of a smooth manifold $M$ to be lifted to a linear automorphism of a given real vector bundle $p : V \to M$ , are stated. Examples are includ…

Invariants for the Lagrangian Equivalence Problem

Marco Castrillón López, Jaime Muñoz Masqué, Eugenia Rosado María

Let $M$ be a connected smooth manifold, let $Aut (p)$ be the group automorphisms of the bundle $p : R \times M \to R$ , and let $q\colon J^1(\mathb…

Geometric structures associated with the Chern connection attached to a SODE

J. Muñoz-Masqué, E. Rosado María

To each second-order ordinary differential equation $σ$ on a smooth manifold $M$ a $G$ -structure $P^{σ}$ on $J^{1} (R, M)$ is associated and the Chern connection $\nabla^{σ}$ att…
