Popis: In a recent discussion E. A. Desloge has performed an analysis of the kinematic nonequivalence of a uniformly accelerating reference frame (UAR) and a frame at rest in a uniform gravitational field (UGF). Desloge considered two-dimensional space-times. We here review the geometrical description of gravity in two, three, and four space-time dimensions in order to discuss thedynamical nonequivalence of UAR and UGF both in two and in four space-time dimensions. We also consider the motion of photons in UAR and UGF in order to illustrate some relativistic effects of a kinematic nature.
