A model of gauge theory with invariant variables. (English) Zbl 1105.83302
Summary: A model for $$SU$$(2) gauge theory with invariant variables is presented. The strength tensor of the $$SU$$(2) gauge potentials and its Hodge dual are obtained for a spherical symmetric model. Then, a metric tensor associated to these tensors is constructed. The components of this metric tensor are interpreted as gauge invariant variables for $$SU$$(2) theory. The property of self -duality of the gauge model with respect to the metric tensor is studied. The self-duality equations are written and their solution is obtained. A comparison with the Yang-Mills field equations is also given.
