Characterization of Orlicz–Sobolev space. (English) Zbl 1166.46308
Summary: We give a new characterization of the Orlicz–Sobolev space \(W ^{1,\Psi}(\mathbb{R}^n)\) in terms of a pointwise inequality connected to the Young function \(\Psi\). We also study different Poincaré inequalities in the metric measure space.
