Resumen de On a singular perturbation problem involving a "circular-well" potential

Nelly André, Itai Shafrir

• We study the asymptotic behavior, as a small parameter goes to 0, of the minimizers for a variational problem which involves a "circular-well" potential, i.e., a potential vanishing on a closed smooth curve in R2. We thus generalize previous results obtained for the special case of the Ginzburg-Landau potential.
