Abstract
We have measured the metric size function η(r) defined by Petrosian on a limited sample of luminous distant galaxies, up to a redshift of 1.175. Although our investigation has a preliminary character, we find some evidence for the evolution of elliptical galaxies. Using the Ostriker-Hausman theoretical models, we place some constraints on the rates of dynamical evolution. The eta function appears to be an extremely sensitive probe for the investigation of galactic evolution and potentially useful in cosmology. Some problems and directions for future work are outlined.
