Polynomial duality-symmetric lagrangians for free p-forms

Abstract We explore the properties of polynomial Lagrangians for chiral p -forms previously proposed by last named author, and in particular, provide a self-contained treatment symmetries equations motion that shows great economy simplicity this formalism. further use analogous techniques to construct democratic general where electric magnetic potentials appear on equal footing as explicit dynamical variables. Due our reliance differential form notation, construction is compact universally valid forms all ranks, any number dimensions.
