DESCRIPTION:We will analyze the asymptotic behavior of a two-dimensional G
 inzburg-Landau model for gradient fields. The main feature of the model co
 nsists in the nucleation of line-defects on which the energy concentrates.
  We develop the concept of entropies coming from scalar conservation laws 
 in order to carry on the asymptotic analysis and to characterize the limit
  line-energies. We will also discuss the structure of minimizing configura
 tions.\n
