  We investigate BPS conditions preserving n/12 (n = 1,...,6) supersymmetries
in the Aharony-Bergman-Jafferis-Maldacena (ABJM) model. The BPS equations are
classified in terms of the number of preserved supercharges and remaining
subgroups of the SU(4)_R symmetry. We study structures of a map between
projection conditions for the supercharges in eleven dimensions and those in
the ABJM model. The BPS configurations in the ABJM model can be interpreted as
known BPS objects in eleven-dimensional Mtheory,such as intersecting M2,
M5-branes, M-waves, KK-monopoles and M9-branes. We also show that these BPS
conditions reduce to those in N = 8 super Yang-Mills theory via the standard
D2-reduction procedure in a consistent way with the M-theory interpretation of
the BPS conditions.
