Analysis reveals bounds for gradient regularity in local–nonlocal problems, highlighting Riesz potential's role.
We study gradient regularity for mixed local–nonlocal problems modeled upon for and , where is a bounded Borel measure and is the ambient dimension. We prove pointwise bounds for the gradient in terms of the truncated 1‐Riesz potential of .
