Geometry of extended Bianchi-Cartan-Vranceanu spaces
Angel Ferrández, Antonio M. Naveira, Ana D. Tarrío
The differential geometry of -dimensional Bianchi, Cartan and Vranceanu () spaces is well known. We introduce the extended Bianchi, Cartan and Vranceanu () spaces as…

Decoupling between torsion and magnetic fields in bouncing cosmology and galactic dynamo seeds
Garcia de Andrade, Angel Ferrandez
Recently Salim et al [JCAP (2007)], have shown that galactic dynamo seeds can be possibly attainable in bouncing cosmological models with QED Lagrangeans. In this paper we generali…

Geometrical particle models on 3D null curves
Angel Ferrandez, Angel Gimenez, Pascual Lucas
The simplest (2+1)-dimensional mechanical systems associated with light-like curves, already studied by Nersessian and Ramos, are reconsidered. The action is linear in the curvatur…
