Dualisation of the D = 9 Matter Coupled Supergravity
(Springer, 2005) Yilmaz, NT
We perform the bosonic dualisation of the matter coupled N ≤ 1, D ≤ 9 supergravity. We derive the Lie superalgebra which parameterizes the coset map whose Cartan form realizes the second-order bosonic field equations. Following the non-linear coset construction we present the first-order formulation of the bosonic field equations as a twisted self-duality condition. © SISSA 2005.

Dualisation of the D=7 Heterotic String -: Art. No. 003
(Springer, 2004) Yilmaz, NT; Yilmaz, NT
The dualisation and the first-order formulation of the D = 7 abelian Yang-Mills supergravity which is the low energy effective limit of the D = 7 fully Higssed heterotic string is discussed. The non-linear coset formulation of the scalars is enlarged to include the entire bosonic sector by introducing dual fields and by constructing the Lie superalgebra which generates the dualized coset element.

Dualisation of the Symmetric Space Sigma Model With Couplings
(Elsevier Science Bv, 2005) Dereli, T; Yilmaz, NT
The first-order formulation of the G/K symmetric space sigma model of the scalar cosets of the supergravity theories is discussed when there is coupling of (m - 1)-form matter fields. The Lie superalgebra which enables the dualized coset formulation is constructed for a general scalar coset G/K with matter coupling where G is a non-compact real form of a semi-simple Lie group and K is its maximal compact subgroup.

Nonlinear Realization of Pure N=4,d=5 Supergravity -: Art. No. 105013
(Amer Physical Soc, 2005) Yilmaz, NT
We perform the nonlinear realization or the coset formulation of the pure N=4, D=5 supergravity. We derive the Lie superalgebra which parameterizes a coset map whose induced Cartan-Maurer form produces the bosonic field equations of the pure N=4, D=5 supergravity by canonically satisfying the Cartan-Maurer equation. We also obtain the first-order field equations of the theory as a twisted self-duality condition for the Cartan-Maurer form within the geometrical framework of the coset construction.
