Abstract: In this note we summarize some of the quantum properties found since theearly 80-s until nowdays that characterize at quantum level the spectrum of thesupermembrane. In particular we will focus on a topological sector of the 11Dsupermembrane that, contrary to the general case, has a purely discretespectrum at supersymmetric level. This construction has been consistentlyimplemented in different types of backgrounds: toroidal and orbifold-type withG2 structure able to lead to a true G2 compactification manifold. This theoryhas N=1 supersymmetries in 4D. comment on the relevant points of thisconstruction as well as on its spectral characteristics. We will also make somecomments on the quantum properties of some effective formulation of multipleM2-s theories recently found.
