ABSTRACT. In these notes I will briefly summarize our knowledge
about the dark matter problem, and emphasize the corresponding dynamical
aspects. This covers a wide area of research, so I have been selective, and
have concentrated on the subject of dark matter in nearby galaxies,
in particular spirals.
KEY WORDS: Galaxies, Dark Matter
