We pursue the study of a model convex functional with orthotropic structure and nonstandard growth conditions, this time focusing on the sub -quadratic case. We prove that bounded local minimizers are locally Lipschitz. No restrictions on the ratio between the highest and the lowest growth rates are needed. The result holds also in presence of a non -autonomous lower order term, under sharp integrability assumptions. Finally, we prove higher differentiability of bounded local minimizers as well.

Abstract
We pursue the study of a model convex functional with orthotropic structure and nonstandard growth conditions, this time focusing on the sub -quadratic case. We prove that bounded local minimizers are locally Lipschitz. No restrictions on the ratio between the highest and the lowest growth rates are needed. The result holds also in presence of a non -autonomous lower order term, under sharp integrability assumptions. Finally, we prove higher differentiability of bounded local minimizers as well.File in questo prodotto:
