Lorentz Violation in Extra Dimensions ∗ †
In theories with extra dimensions it is well known that the Lorentz invariance of the D = 4 + n-dimensional spacetime is lost due to the compactified nature of the n dimensions leaving invariance only in 4d. In such theories other sources of Lorentz violation may exist associated with the physics that initiated the compactification process at high scales. Here we consider the possibility of cap...

From the Lorentz Transformation Group in Pseudo-Euclidean Spaces to Bi-gyrogroups
The Lorentz transformation of order $(m=1,n)$, $ninNb$, is the well-known Lorentz transformation of special relativity theory. It is a transformation of time-space coordinates of the pseudo-Euclidean space $Rb^{m=1,n}$ of one time dimension and $n$ space dimensions ($n=3$ in physical applications). A Lorentz transformation without rotations is called a {it boost}. Commonly, the ...
متن کاملThe Violation of Remaining Lorentz Symmetry in the Approach of TOPT to Space-Time Noncommutativity
We study remaining Lorentz symmetry, i.e. Lorentz transformations which leave the noncommutativity parameter θ invariant, within the approach of TOPT to space-time noncommutative theories. Their violation is shown in a simple scattering process. We argue that this results from the non-covariant transformation properties of the phase factors appearing in TOPT. PACS: 11.10.Nx, 11.30.Cp
متن کاملInertiality Implies the Lorentz Group
In his seminal paper of 1905, Einstein derives the Lorentz group as being the coordinate transformations of Special Relativity, under the main assumption that all inertial frames are equivalent. In that paper, Einstein also assumes the coordinate transformations are linear. Since then, other investigators have weakened and varied the linearity assumption. In the present paper, we retain only th...
