QUASAR REDSHIFTS IN ISO-MINKOWSKI SPACES

We suggest a possible interpretation of the large redshifts of quasars in terms of a deformation of their interior metric, based on Santilli's Lie-isotopic lifting of special relativity. The Lie-isotopic Doppler effect is due to the inhomogeneity and anisotropy of the hyperdense quasar's atmosphere. Numerical estimates are derived from available astrophysical data, which indicate a possible revision of the speed of quasars with respect to the associated galaxy, while leaving current views on the expansion of the universe completely unaffected.
