Article Citation - WoS: 1Citation - Scopus: 1Symmetric Space Σ-Model Dynamics: Current Formalism(World Scientific Publ Co Pte Ltd, 2007) Yilmaz, Nejat T.After explicity constructing the symmetric space sigma model Lagrangian in terms of the coset scalars of the solvable Lie algebra gauge in the current formalism, we derive the field equations of the theory.Article Citation - WoS: 1Citation - Scopus: 1Dualization of the Principal Sigma Model(Amer inst Physics, 2008) Yilmaz, Nejat T.; Ylmaz, Nejat T.The first-order formulation of the principal sigma model with a Lie group target space is performed. By using the dualization of the algebra and the field content of the theory the field equations which are solely written in terms of the field strengths are realized through an extended symmetry algebra parametrization. The structure of this symmetry algebra is derived so that it generates the realization of the field equations in a Bianchi identity of the current derived from the extended parametrization.

The bosonic field equations are regained through the Cartan-Maurer equation which the Cartanformsatisfies.The first-orderformulationofthetheoryisalsoobtainedasa twisted self-duality condition within the nonlinear coset construction.
