Partial regularity for $\mathbb{A}$-quasiconvex functionals with Orlicz growth

We establish partial regularity results for minimizers of a class of functionals depending on differential expressions based on elliptic operators. Specifically, we focus on functionals of Orlicz growth with a natural strong quasiconvexity property. In doing so, we consider both ${\mathrm{\Delta }}_2\cap {\mathrm{\nabla }}_2$-Orlicz growth scenarios and, as a limiting case, $L\log L$-growth. Inspired by Conti & Gmeineder (J Calc Var, 61:215, 2022), the proofs of our main results are accomplished by reduction to the case of full gradient partial regularity results.
