De Sitter Special Relativity
A special relativity based on the de Sitter group is introduced. Like ordinary special relativity, it retains the quotient character of spacetime, and consequently a notion of homogeneity. This means that the underlying spacetime will be a de Sitter spacetime, the quotient space between de Sitter and the Lorentz groups. Since the local symmetry will also be given by the de Sitter group, each ta...
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 کاملSpecial Relativity
References 43 Index 45 ii Preface For me, the wonder of special relativity lies in its successful prediction of interesting and very nonintuitive phenomena from simple arguments with simple premises. These notes have three (perhaps ambitious) aims: (a) to introduce undergraduates to special relativity from its founding principle to its varied consequences, (b) to serve as a reference for those ...
متن کاملSpecial Relativity
Inertial frames are frames related by a constant velocity along any axis. An object is at rest in an inertial frame when its position in space does not change with time. We consider two inertial frames: the 26-100 (S) frame in which we are at rest and the Space Shuttle frame (S ′) which moves relative to S with a velocity u along the x axis and in which the Shuttle is at rest. Newton postulated...
متن کامل2 00 3 Doubly Special Relativity and de Sitter space
In this paper we recall the construction of Doubly Special Relativity (DSR) as a theory with energy-momentum space being the four dimensional de Sitter space. Then the bases of the DSR theory can be understood as different coordinate systems on this space. We investigate the emerging geometrical picture of Doubly Special Relativity by presenting the basis independent features of DSR that includ...
