On the embedding of spacetime in higher-dimensional spaces with torsion
C. Romero, J. B. Formiga, L. F. P. da Silva +1
We revisit the Riemann-Cartan geometry in the context of recent higher-dimensional theories of spacetime. After introducing the concept of torsion in a modern geometrical language…

On the spectral shift and the time delay of light in a Rindler accelerated frame
J. B. Formiga, C. Romero
We discuss two effects predicted by the general theory of relativity in the context of Rindler accelerated observers: the gravitational spectral shift and the time delay of light.…

On the differential geometry of curves in Minkowski space
J. B. Formiga, C. Romero
We discuss some aspects of the differential geometry of curves in Minkowski space. We establish the Serret-Frenet equations in Minkowski space and use them to give a very simple pr…
