# The Relativistic Composite-Velocity Reciprocity Principle

@article{Ungar2000TheRC, title={The Relativistic Composite-Velocity Reciprocity Principle}, author={A. Ungar}, journal={Foundations of Physics}, year={2000}, volume={30}, pages={331-342} }

Gyrogroup theory [A. A. Ungar, Found. Phys. 27, 881–951 (1997)] enables the study of the algebra of Einstein's addition to be guided by analogies shared with the algebra of vector addition. The capability of gyrogroup theory to capture analogies is demonstrated in this article by exposing the relativistic composite-velocity reciprocity principle. The breakdown of commutativity in the Einstein velocity addition ⊕ of relativistically admissible velocities seemingly gives rise to a corresponding… Expand
