Abstract
Let \({\Omega\subset\mathbb{R}^n}\) be open and bounded. For 1 ≤ p < ∞ and 0 ≤ λ < n, we give a characterization of Young measures generated by sequences of functions \({\{{\bf f}_j\}_{j=1}^\infty}\) uniformly bounded in the Morrey space \({L^{p,\lambda}(\Omega;\mathbb{R}^N)}\) with \({\{\left|{{\bf f}_j}\right|^p\}_{j=1}^\infty}\) equiintegrable. We then treat the case that each f j = ∇ u j for some \({{\bf u}_j\in W^{1,p}(\Omega;\mathbb{R}^N)}\). As an application of our results, we consider the functional
and provide conditions that guarantee the existence of a minimizing sequence with gradients uniformly bounded in \({L^{p,\lambda}(\Omega;\mathbb{R}^{N\times n})}\).
