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 $X^{\mu }=x^{\mu }/[1+a_{\nu }{x}^{\nu }/R]$, where $R$ is a…
