Abstract

Observations about dynamical aspects of compact groups of galaxies are reviewed, and N-body numerical simulations are applied in order to lend theoretical interpretations to the observational results. In connection with dynamical evolution time scale the possible importance of an extended massive dark matter envelope is pointed out in which a compact galaxy group is embedded.
