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 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 to be lifted to a linear automorphism of a given real vector bundle , are stated. Examples are includ…
Invariants for the Lagrangian Equivalence Problem
Marco Castrillón López, Jaime Muñoz Masqué, Eugenia Rosado María
Let be a connected smooth manifold, let be the group automorphisms of the bundle , 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 on a smooth manifold a -structure on is associated and the Chern connection att…
