The Lanczos potential in the Plebanski paradigm of gravity
Daniel Espín, Alejandro Jiménez Cano, Javier Olmedo +1
We present a new Plebanski formulation of General Relativity. The key difference is that we work with a gauge vector field derived from the Lanczos potential of the Weyl tensor. We…

Cosmological Spacetimes with Sign-Changing Spatial Curvature and Topological Transitions
Gerardo García-Moreno, Bert Janssen, Alejandro Jiménez Cano +3
Observational evidence, together with practical computations and modeling, supports a Euclidean spatial sector in the current cosmological model based on the FLRW metric. This, how…
