Extension of ChernSimons forms
We investigate metric independent, gauge invariant, and closed forms in the generalized YangMills (YM) theory. These forms are polynomial on the corresponding fields strength tensors ??? curvature forms and are analogous to the PontryaginChern densities in the YM gauge theory. The corresponding secondary characteristic classes have been expressed in integral form in analogy with the ChernSimons form. Because they are not unique, the secondary forms can be dramatically simplified by the addition of properly chosen differentials of onesteplowerorder forms. Their gauge variation can also be found yielding the potential anomalies in the gauge field theory.
