DE SITTER TRANSITIVITY, CONFORMAL TRANSFORMATIONS AND CONSERVATION LAWS
(World Scientific Publ Co Pte Ltd, 2014-04-01)
Minkowski spacetime is transitive under ordinary translations, a transformation that do not have matrix representations. The de Sitter spacetime, on the other hand, is transitive under a combination of translations and ...

de Sitter geodesics: reappraising the notion of motion
(Springer/plenum Publishers, 2012-05-01)
The de Sitter spacetime is transitive under a combination of translations and proper conformal transformations. Its usual family of geodesics, however, does not take into account this property. As a consequence, there are ...

From de sitter to de sitter: a non-singular inflationary universe driven by vacuum
(International Journal of Modern Physics D, 2006)
A semi-classical analysis of vacuum energy in the expanding space–time suggests that
the cosmological term decays with time, with a concomitant matter production. For
early times we find, in Planck units, Λ ≈ H4, where H ...

Chemical potential driven phase transition of black holes in anti-de Sitter space
(American Physical Society, 2015-11)
Einstein-Maxwell theory conformally coupled to a scalar field in D dimensions may exhibit a phase transition at low temperature whose end point is an asymptotically anti-de Sitter black hole with a scalar field profile ...
A Fixed-wing UAV Capable of Vertical Take-off and Landing for Aerial Mapping and Photogrammetry.

Transitividade e movimento em relatividade de de Sitter
(Universidade Estadual Paulista (Unesp), 2013-12-18)
There are currently an agreement that special relativity, whose kinematic is ruled by the Poincaré group, fails near the Planck scale. As a consequence, new kinematics have been proposed. An alternative to those theories ...
