Article Citation - WoS: 2Citation - Scopus: 2On the Symmetric Space Sigma;-Model Kinematics(World Scientific Publishing Co. Pte Ltd, 2007) Yilmaz, N.T.; Yilmaz, N.T.The solvable Lie algebra parametrization of the symmetric spaces is discussed. Based on the solvable Lie algebra gauge two equivalent formulations of the symmetric space sigma model are studied. Their correspondence is established by inspecting the normalization conditions and deriving the field transformation laws. © World Scientific Publishing Company.Article Decoupling Structure of the Principal Sigma Model-Maxwell Interactions(Academic Press inc Elsevier Science, 2008) Yilmaz, Nejat T.The principal sigma model and Abelian gauge fields coupling is studied. By expressing the first-order formulation of the gauge field equations an implicit on-shell scalar-gauge field decoupling structure is revealed. It is also shown that due to this decoupling structure the scalars of the theory belong to the pure sigma model and the gauge fields sector consists of a number of coupled Maxwell theories with currents partially induced by the scalars.
