Query: Supersymmetric objects in the M-theory on a pp-wave   We obtain, in a systematic way, all the classical BPS equations which
correspond to the quantum BPS states in the M-theory on a fully supersymmetric
pp-wave. The superalgebra of the M-theory matrix model shows that the BPS
states always preserve pairs of supersymmetry, implying the possible fractions
of the unbroken supersymmetry as 2/16, 4/16, 6/16,.... We study their classical
counterparts, and find there are essentially one unique set of 2/16 BPS
equations, three inequivalent types of 4/16 BPS equations, and three
inequivalent types of 8/16 BPS equations only, in addition to the 16/16 static
fuzzy sphere. We discuss various supersymmetric objects as solutions. In
particular, when the fuzzy sphere rotates, the supersymmetry is further broken
as 16/16 -> 8/16 -> 4/16.
