Abstract:
For a one-dimensional nonlocal nonconvex singular perturbation problem with a noncoercive periodic well potential, we prove a formula3-convergence theorem and show compactness up to translation in all formula5 and certain Orlicz spaces for sequences of bounded energy. This generalizes work of Alberti, Bouchitté and Seppecher for the coercive two-well case. The theorem has applications to a certain thin-film limit of the micromagnetic energy.
