The influence of the environment in the formation of the galaxies we see today is still a key question. The mechanisms involved an the moment at which they occur in the field or in clusters and groups of galaxies have not been clearly identified yet. In this context the study of stellar systems belonging to high and low density environments becomes relevant to provide clues about these important issues.In particular, the study of compact groups is interesting as their galaxy space density is similar to that found in the central regions of rich clusters. In addition, they show low velocity dispersions which allow to observe gravitational interactions in progress.
