Michel's theorem and critical section
of gauge functionals
(100K, Plain TeX)
ABSTRACT. In many physical problems, one has to minimize a G-invariant
potential, i.e. a potential invariant under the action of a symmetry
group. In this case a powerful tool is offered by a theorem of L. Michel and
generalizations thereof. The purpose of this note
is to discuss just another such generalization, to gauge potentials.
