A logic road from special to general relativity [PDF]
, 2010 We present a streamlined axiom system of special relativity in firs-order logic. From this axiom system we ``derive'' an axiom system of general relativity in two natural steps.

Moving Unstable Particles and Special Relativity
Advances in High Energy Physics, 2018 In Poincaré-Wigner-Dirac theory of relativistic interactions, boosts are dynamical. This means that, just like time translations, boost transformations have a nontrivial effect on internal variables of interacting systems.

Discussions on Special and General Relativity Model
Chaos Theory and Applications, 2021 In this study, the Michelson–Morley experiment and the result of this experiment (the speed of light appears to be the same in all directions) were explored.

Holographic special relativity [PDF]
Advances in Theoretical and Mathematical Physics, 2015 We reinterpret special relativity, or more precisely its de Sitter deformation, in terms of 3d conformal geometry, as opposed to (3+1)d spacetime geometry. An inertial observer, usually described by a geodesic in spacetime, becomes instead a choice of ways to reverse the conformal compactification of a Euclidean vector space up to scale. The observer's

Annalen der Physik, 2008 Abstract In the special theory of relativity, Lorentz invariance is extended in Minkowski spacetime from ideal inertial observers to actual observers by means of the hypothesis of locality, which postulates that accelerated observers are always pointwise inertial. A critical examination of the locality assumption reveals its domain of

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Renormalization of Very Special Relativity gauge theories
Journal of High Energy Physics, 2023 Mandelstam-Leibbrandt (ML) regularization of Very Special Relativity (VSR) amplitudes in momentum space depends on two fixed null vectors n μ , n ¯ μ $$ {\overline{n}}_{\mu } $$ besides external momenta. ML is known to preserve gauge invariance and naive
