Subject: How Many Distinct Invariants of the Poincaré Group Can you derive?
Poincaré lists 8 distinct but elementary invariants in his paper, ON
THE DYNAMICS OF THE ELECTRON. See the equation number 5 and 7 in http://www.univ-nancy2.fr/poincare/bhp/pdf/hp2007gg.pdf How many invariants in special relativity are you aware of? How many distinct invariants of the Poincaré group exist? And how many distinct invariants of the Poincaré group can you derive? This is how mathematicians measure the understanding of physicists in spacetime. I quote: "Every geometry is defined by a group of transformations, and the goal "Each type of geometry is the study of the invariants of a group of "A geometry is defined by a group of transformations, and investigates "The geometry of Minkowski space is defined by the Poincaré group."
