TITLE: A closeness result for the class of deformations in the presence 
of dislocations.

ABSTRACT: We consider the energy of a single crystal with dislocations, 
and want to minimize it among a suitably large class of deformations and 
dislocations satisfying some boundary condition. Assuming the energy
depending on the crystal deformation via a polyconvex function and on 
the dislocations density with some coerciveness conditions, we prove a 
closeness and compactness result for a big class of competitors, by 
studying the graphs of the deformations seen as 3-currents in Omega X R^3.
