Generalized Fock--Lorentz Transformations from Projective Conformal Coordinates: Covariant Structure, Sector Classification, and Oscillator Limits

Abdelmalek Boumali, N. Jafari, M. Botshekananfard

We develop a covariant projective formulation of generalized Fock--Lorentz (GFL) transformations based on the auxiliary Minkowski coordinates $X^{\hat{I}}¼=x^{\hat{I}}¼/[1+a_{\hat{I}}½x^{\hat{I}}½/R]$, where $R$…
