Length measurement in accelerated systems
Bahram Mashhoon, Uwe Muench
We investigate the limitations of length measurements by accelerated observers in Minkowski spacetime brought about via the hypothesis of locality, namely, the assumption that an a…
Acceleration-Induced Nonlocal Electrodynamics in Minkowski Spacetime
Uwe Muench, Friedrich W. Hehl, Bahram Mashhoon
We discuss two nonlocal models of electrodynamics in which the nonlocality is induced by the acceleration of the observer. Such an observer actually measures an electromagnetic fie…
A small guide to variations in teleparallel gauge theories of gravity and the Kaniel-Itin model
Uwe Muench, Frank Gronwald, Friedrich W. Hehl
Recently Kaniel & Itin proposed a gravitational model with the wave type equation [\square+λ(x)]\vartheta^α=0 as vacuum field equation, where \vartheta^αdenotes the coframe of spac…
Volume elements of spacetime and a quartet of scalar fields
Frank Gronwald, Uwe Muench, Alfredo Macías +1
Starting with a `bare' 4-dimensional differential manifold as a model of spacetime, we discuss the options one has for defining a volume element which can be used for physical theo…
A note on post-Riemannian structures of spacetime
Friedrich W. Hehl, Uwe Muench
A four-dimensional differentiable manifold is given with an arbitrary linear connection . Megged has claimed that he can define a metric by means of a…
