abstract

We obtain optimal regularity results for solutions to vectorial $p$-Laplace equations $$ -{\boldsymbol \Delta}_p{\boldsymbol u}=-\operatorname{\bf div}(|D{\boldsymbol u}|^{p-2}D{\boldsymbol u}) = {\boldsymbol f}(x)\,\, \mbox{ in $\Omega$}\,.$$ More precisely we address the issue of global second order estimates for the stress field.

  1. Regularity results for elliptic equations on cones

    math.AP 2026-07 conditional novelty 6.0 of 10

    Gradient boundedness in spherical cones holds precisely when the first nontrivial cross-sectional Laplacian eigenvalue is ≥ N−1; weighted Lipschitz and second-order estimates hold for p-Laplace equations.

  2. Second-order boundary estimates for solutions to a class of quasilinear elliptic equations

    math.AP 2025-07 conditional novelty 6.0 of 10

    For quasilinear equations -div(a(|∇u|)∇u)=f, the stress field a(|∇u|)^k∇u is shown to belong to W^{1,2}(Ω) up to the boundary for the optimal range of k, under weak W^{2,X} boundary regularity, with a convex-domain ve...

  3. Existence results for variational quasilinear elliptic systems involving the vectorial $p$-Laplacian

    math.AP 2025-10 conditional novelty 5.0 of 10

    All least-energy solutions of the vectorial p-Laplacian Lane–Emden system are of the form (c^1 ω, …, c^m ω), where c is a unit vector and ω solves the scalar p-Laplacian equation.
