Giant magnon and spike solutions with two spins in AdS4 x CP3

In the string theory in AdS(4) x CP3 we construct the giant magnon and spike solutions with two spins in two kinds of subspaces of R-t x CP3 and derive the dispersion relations for them. For the single giant magnon solution in one subspace we show that its dispersion relation is associated with that of the big one-spin giant magnon solution in the RP2 subspace. For the single giant magnon solution in the other complementary subspace its dispersion relation is similar to that of the one-spin giant magnon solution living in the S-2 subspace but has one additional spin dependence.
