The N = 1 self-dual supergravity has SL(2,C) symmetry and the lefthanded and right-handed local supersymmetries. These symmetries result in SU(2) charges as the angular-momentum and the supercharges. The model possesses also the invariance under the general translation transforms and this invariance leads to the energy-momentum. All the definitions are generally covariant. As the SU(2) charges ...

We generalize the M-theoretic duality of Schmaltz and Sundrum to the product group SU(N)×SU(N ) case. We show that the type IIA brane configurations for dual gauge theories are in fact two special limits of the same M-theory 5-brane, just as in the case of the simple SU(N) group. : [email protected] : [email protected]
