A Möbius-Scale Spinor Lift of Lorentz Kinematics: The Contained-Volume Law for Four-Momentum

Lorentz transformations are linear on Minkowski spacetime but induce Möbius maps on velocity, null-direction, celestial, and spinor ratios. Starting from this correspondence, we introduce the active model lift B = λA ∈ GL(2,ℂ), with A ∈ SL(2,ℂ) and κ = |λ|. The scalar factor does...
