Dualisation of the symmetric space sigma model with couplings Original Research Article

The first-order formulation of the image symmetric space sigma model of the scalar cosets of the supergravity theories is discussed when there is coupling of (image)-form matter fields. The Lie superalgebra which enables the dualized coset formulation is constructed for a general scalar coset image with matter coupling where G is a non-compact real form of a semi-simple Lie group and K is its maximal compact subgroup.
