A regularized model of the double compactified D=11 supermembrane with nontrivial winding in terms of SU(N) valued maps is obtained. The condition of nontrivial winding is described in terms of a nontrivial line bundle introduced in the formulation of the compactified supermembrane. The multivalued geometrical objects of the model related to the nontrivial(More)
The spectrum of the bosonic sector of the D = 11 Supermembrane with central charges is shown to be discrete with finite multiplicity, hence containing a mass gap. This result extends to the exact theory our previous proof of a similar result for the SU(N) regularized model. Based on these and other previous results, it is also argued that the same(More)
The action of the 11D supermembrane with nontrivial central charges compactified on a 7D toroidal manifold is obtained. It describes a supermembrane immersed in a 4d Minkowski space-time. The action is invariant under additional symmetries in comparison to the supermembrane on a Minkowski target space. The hamiltonian in the LCG is invariant under conformal(More)
