abstract

We study gradient regularity for mixed local-nonlocal problems modelled upon \[ -\Delta_p u +(-\Delta_p)^su=\mu\qquad\text{for} \quad 2-\tfrac{1}{n}<p<\infty\quad \text{and}\quad s\in(0,1)\,,\] where $\mu$ is a bounded Borel measure. We prove pointwise bounds for the gradient $Du$ in terms of the truncated 1-Riesz potential of $\mu$.

  1. Higher Sobolev regularity on the mixed local and nonlocal p-Laplace equations

    math.AP 2025-01 conditional novelty 6.0 of 10

    For mixed local and nonlocal p-Laplace equations, weak solutions inherit the same higher Sobolev regularity as classical p-harmonic functions: W^{2,2}_loc for 1<p≤2 and |∇u|^{(p-2)/2}∇u in W^{1,2}_loc for p≥2.

  2. Regularity and existence for semilinear mixed local-nonlocal equations with variable singularities and measure data

    math.AP 2024-12 conditional novelty 6.0 of 10

    Existence and regularity are established for semilinear mixed local-nonlocal problems with variable singular exponent and measure-valued data, including the case of two simultaneous measure sources.
