Manifold-constrained free discontinuity problems and Sobolev approximation
Federico Luigi Dipasquale, Bianca Stroffolini
We study the regularity of local minimisers of a prototypical free-discontinuity problem involving both a manifold-valued constraint on the maps (which are defined on a bounded dom…

The Yang-Mills-Higgs functional on complex line bundles: asymptotics for critical points
Giacomo Canevari, Federico Luigi Dipasquale, Giandomenico Orlandi
We consider a gauge-invariant Ginzburg-Landau functional (also known as Abelian Yang-Mills-Higgs model) on Hermitian line bundles over closed Riemannian manifolds of dimension $n \…

Torus-like solutions for the Landau-de Gennes model. Part I: the Lyuksyutov regime
Federico Dipasquale, Vincent Millot, Adriano Pisante
We study global minimizers of a continuum Landau-De Gennes energy functional for nematic liquid crystals, in three-dimensional domains. Assuming smooth and uniaxial (e.g. homeotrop…
