متن کاملVery Special Relativity and TGD
One might think that Poincare symmetry is something thoroughly understood but the Very Special Relativity [1] proposed by nobelist Sheldon Glashow and Andrew Cohen suggests that this might belief might be wrong. Glashow and Cohen propose that instead of Poincare group, call it P , some subgroup of P might be physically more relevant than the whole P . To not lose four-momentum one must assume t...
متن کاملDe Sitter Special Relativity: Effects on Cosmology
The main consequences of de Sitter Special Relativity to the Standard Model of Physical Cosmology are examined. The cosmological constant Λ appears, in this theory, as a manifestation of the proper conformal current, which must be added to the usual energy–momentum density. As that conformal current itself vanishes in absence of sources, Λ is ultimately dependent on the matter content, and can ...
متن کاملVery Special Relativity in Curved Space-Times
The generalization of Cohen and Glashow’s Very Special Relativity to curved space-times is considered. Gauging the SIM(2) symmetry does not, in general, provide the coupling to the gravitational background. However, locally SIM(2) invariant Lagrangians can always be constructed. For space-times with SIM(2) holonomy, they describe chiral fermions propagating freely as massive particles.
متن کاملRiemannian collineations in General Relativity and in Einstein-Cartan cosmology
Riemannian vectorial collineations along with current Killing conservation are shown to lead to tensorial collineations for the energystress tensor in general relativity and in Einstein-Cartan Weyssenhoff fluid cosmology.
