The distance formula in algebraic spacetime theories
arXiv:1902.00591 · doi:10.1088/1742-6596/1275/1/012045
Abstract
The Lorentzian distance formula, conjectured several years ago by Parfionov and Zapatrin, has been recently proved by the second author. In this work we focus on the derivation of an equivalent expression in terms of the geometry of 2-spinors by using a partly original approach due to the first author. Our calculations clearly show the independence of the algebraic distance formula of the observer.
