A bstract We reconsider the supermembrane in a Minkowski background and in the light-
cone gauge as a one-dimensional gauge theory of area preserving diffeomorphisms …

We analyze the Hamiltonian of the compactified D= 11 supermembrane with nontrivial
central charge in terms of the matrix model constructed in [Phys. Rev. D 66 (2002) 045023 …

We give the explicit formulation of the 11D supermembrane as a symplectic torus bundle
with non trivial monodromy and non vanishing Euler class. This construction allows a …

We formulate a general sufficiency criterion for discreteness of the spectrum of both
supersymmmetric and non-supersymmetric theories with a fermionic contribution. This …

We construct an 11D supermembrane with topological central charges induced through an
irreducible winding on a G2 manifold realized from the T 7/Z 3 2 orbifold construction. The …

A bstract The M-theory origin of the IIB gauged supergravities in nine dimensions, classified
according to the inequivalent classes of monodromy, is shown to exactly corresponds to the …

We construct the Hamiltonian of the D= 11 supermembrane with topological conditions on
configuration space. It may be interpreted as a supermembrane theory where all …

We study the quantization of the regularized Hamiltonian, H, of the compactified D= 11
supermembrane with non-trivial winding. By showing that H is a relatively small perturbation …

The SL (2, Z) duality symmetry of IIB superstring is naturally realized on the D= 11
supermembrane restricted to have central charges arising from a nontrivial wrapping. This …

The spectrum of the bosonic sector of the D= 11 supermembrane with central charges is
shown to be discrete and with finite multiplicities, hence containing a mass gap. The result …
