SESZIONE DI TORINO
During the talk I will review the main features associated to the 11D supermembrane minimally immersed (MIM2). Its properties are completely different to those of the 11D supermembrane. I will show briefly how the theory may be formulated on a G2 manifold in 4d with N=1 supersymmetry. This theory is quantum consistent. I will derive directly from the mass spectrum, of the MIM2, the tower of (F1, Dp) states of type IIB theory. The results coincide exactly with those conjectured by Schwarz and also found by conformal techniques in hep-th/9906214. I will also show the existence of a tower of nonperturbative dyonic states on IIA theory.
