Lorentzian manifolds properly isometrically embeddable in Minkowski spacetime
E. Minguzzi
I characterize the Lorentzian manifolds properly isometrically embeddable in Minkowski spacetime (i.e. the Lorentzian submanifolds of Minkowski spacetime that are also closed subse…
Hints at a relationship between friction and relativistic physics
E. Minguzzi
In applied mechanics Reye's law (1860) establishes, via energy arguments, that the mass of the debris produced by dry friction in the contact of rigid bodies is proportional to the…
An anisotropic gravity theory
A. Garcia-Parrado, E. Minguzzi
We study an action integral for Finsler gravity obtained by pulling back an Einstein-Cartan-like Lagrangian from the tangent bundle to the base manifold. The vacuum equations are o…
Low regularity extensions beyond Cauchy horizons
Martin Lesourd, Ettore Minguzzi
We prove that if in a spacetime endowed with a merely continuous metric, a complete partial Cauchy hypersurface has nonempty Cauchy horizon, then the horizon is caused by the prese…
Surface gravity of compact non-degenerate horizons under the dominant energy condition
Sebastian Gurriaran, Ettore Minguzzi
We prove that under the dominant energy condition any non-degenerate smooth compact totally geodesic horizon admits a smooth tangent vector field of constant non-zero surface gravi…
Projective and amplified symmetries in metric-affine theories
A. García-Parrado, E. Minguzzi
In this paper we extend the projective symmetry of the full metric-affine Einstein-Hilbert theory to a new symmetry transformation in the space of affine connections called the amp…
