The resulting spectrum agrees with that of zero-mode Hamiltonian of a supermembrane theory on the pp-wave background. We also discuss the connection with the Kaluza-Klein zero modes of AdS_4 x S^7 background.17 pages, no figures, LaTeX2e, typos correctedHigh Energy Physics - TheorySpectrum of Eleven-dimensional Supergravity on a PP-wave Backgroundtext
