Título: A short userguide for the study of polyconvex functionals

Resumen: Direct methods of Calculus of Variations are a rigorous framework
to treat mathematically interesting  variational problems arising in science
or engineering. The methods are based on the notion of lower semicontinuity,
which classically is based on the convexity of the integrad  function
however  this assumptions is  unrealistic in the framework of nonlinear
elasticity.
Then  it must be replaced by different and more general conditions, named
quasiconvexity and polyconvexity. In this conference I introduce some new
recent semicontinuity results for non coercive polyconvex functionals.
Moreover we present some existence results for polyconvex and also non
polyconvex  problems, which are related with the Odgen model for Rubberlike
Materials. This existence results are strictly connected with the resolution
of the Prescribed Volume Equation.
Estan todos cordialmente invitados.
