de Sitter Relativity: a New Road to Quantum Gravity?
R. Aldrovandi, J. G. Pereira
The Poincare' group generalizes the Galilei group for high-velocity kinematics. The de Sitter group is assumed to go one step further, generalizing Poincare' as the group governing…
de Sitter Relativity and Quantum Physics
R. Aldrovandi, J. P. Beltran Almeida, C. S. O. Mayor +1
In the presence of a cosmological constant, interpreted as a purely geometric entity, absence of matter is represented by a de Sitter spacetime. As a consequence, ordinary Poincare…
Lorentz transformations in de Sitter relativity
R. Aldrovandi, J. P. Beltran Almeida, C. S. O. Mayor +1
The properties of Lorentz transformations in de Sitter relativity are studied. It is shown that, in addition to leaving invariant the velocity of light, they also leave invariant t…
The Nonlinear Essence of Gravitational Waves
R. Aldrovandi, J. G. Pereira, K. H. Vu
A critical review of gravitational wave theory is made. It is pointed out that the usual linear approach to the gravitational wave theory is neither conceptually consistent nor mat…
Some Implications of the Cosmological Constant to Fundamental Physics
R. Aldrovandi, J. P. Beltran Almeida, J. G. Pereira
In the presence of a cosmological constant, ordinary Poincare' special relativity is no longer valid and must be replaced by a de Sitter special relativity, in which Minkowski spac…
