Abstract
A minimum variational approach is developed for Maxwell's equations. The existence and uniqueness of strong solutions is shown to be equivalent to the existence of a point of strict minimum for an appropriate functional, using some thermodynamical restrictions on the constitutive equations. One of Maxwell's equations is treated as a constraint in defining the domain of such a functional. Suitable functionals are constructed for several cases.File in questo prodotto:
