Regularity results for an optimal design problem with a volume constraint

Menita Carozza, Irene Fonseca, Antonia Passarelli di Napoli (2014)

Similarity:

Regularity results for minimal configurations of variational problems involving both bulk and surface energies and subject to a volume constraint are established. The bulk energies are convex functions with -power growth, but are otherwise not subjected to any further structure conditions. For a minimal configuration (), Hölder continuity of the function is proved as well as partial regularity of the boundary of the minimal set . Moreover, full regularity of the boundary of the minimal...

The polarization in a ferroelectric thin film: local and nonlocal limit problems

Antonio Gaudiello, Kamel Hamdache (2013)

ESAIM: Control, Optimisation and Calculus of Variations

Similarity:

In this paper, starting from classical non-convex and nonlocal 3-variational model of the electric polarization in a ferroelectric material, an asymptotic process we obtain a rigorous 2-variational model for a thin film. Depending on the initial boundary conditions, the limit problem can be either nonlocal or local.
