TY - JOUR T1 - Curvature theory of boundary phases: the two-dimensional case JF - Interfaces Free Bound. 7 (2002) 345-370 Y1 - 2002 A1 - Andrea Braides A1 - Andrea Malchiodi AB - We describe the behaviour of minimum problems involving non-convex surface integrals in 2D, singularly perturbed by a curvature term. We show that their limit is described by functionals which take into account energies concentrated on vertices of polygons. Non-locality and non-compactness effects are highlighted.
