... INTRODUCTION Diffuse (or dwarf) elliptical galaxies are a numerically dominating population in dense regions of the Universe, but their origin and evolution still remain unknown. ...
... INTRODUCTION Integrated photometric and spectral properties of early type galaxies imply that their major stellar population is very old, almost as old as the universe. ...

... INTRODUCTION Lenticular galaxies represent a rather common morphological type in the nearby universe: they constitute up to 15% of all galaxies in the field (Naim et al. 1995), being the second most abundant after spirals. ...
