Dualisation of the general scalar coset in supergravity theories Original Research Article

The dualised formulation of the symmetric space sigma model is peformed for a general scalar coset G/K where G is a maximally non-compact group and K is itʹs maximal compact subgroup. By using the twisted self-duality condition the general form of the first-order equations are obtained. The results are applied to the example of SL(2,R)/SO(2) scalar manifold of the IIB supergravity.
