Einstein’s physical chronogeometry

open access: yesManuscrito
In Einstein’s physical geometry, the geometry of space and the uniformity of time are taken to be non-conventional. However, due to the stipulation of the isotropy of the one-way speed of light in the synchronization of clocks (or definition of ...

Generalized open sets of Minkowski space [PDF]

open access: yesMathematica Moravica, 2015
We consider the Euclidean topology and s-topology on n-dimensional Minkowski space and investigate the interior and closure of the space cone and perforated space cone with respect to these topologies.

Static cosmic strings in space–time with torsion, and strings with electromagnetism

open access: yesNew Journal of Physics, 2016
Cosmic strings are considered in space–time with torsion derived from a two-form potential, and in Minkowski space–time with electromagnetism. Using the curvature scalar as the geometrical part of the Lagrangian density, and the natural coupling to ...

The momentum spaces of κ-Minkowski noncommutative spacetime

open access: yesNuclear Physics B, 2020
A useful concept in the development of physical models on the κ-Minkowski noncommutative spacetime is that of a curved momentum space. This structure is not unique: several inequivalent momentum space geometries have been identified.
