On Isometry Links between 4-Velocity Vectors


Emilija G. Celakovskać




We give an overview on the problem of finding isometry as Lorentz transformation between given vectors of 4-velocity and its solutions. These Lorentz transformations are usually referenced as Lorentz links. We show that the links by boost, obtained independently by different authors in different forms, are identical. Finally, we discuss briefly some implications of the non-uniqueness of boost linking given pair of 4-velocities.
