  The identification of a solution to the dark matter problem has many arrows
to its bow: if dark matter is a new elementary particle, both laboratory
experiments and astrophysics can bring relevant and complementary pieces of
information, that than can be confronted and composed to solve this intriguing
puzzle. Although we currently do not have a unique and obvious target for the
DM particle, we can rely on a broad range of ideas, tools and methods that make
the investigation of dark matter a multi-frequency, multi-messenger and
multi-techniques integrated endeavour.
