On the compactness of the stable set for rate independent processes
This paper deals with a general approach to the rate-independent
processes which may display hysteretic behaviour.This approach
based on the two energy functionals,namely potential and
dissipation functionals.Under some natural assumptions on these
functionals we prove the compactness of the set of stable points
which in turn leads to the existence of solutions of the problems
under consideration.We present an application of our results to
ferromagnetic models.
