Abstract
We consider a class of degenerate/singular elliptic obstacle problems with measure data. The associated differential operator is of p-Laplacian type, p>1, whose coefficient is merely measurable in one variable and has a small BMO seminorm in the other variables. We prove optimal Calderon-Zygmund type estimates for such a problem, without assuming higher differentiability of the obstacle function. (c) 2024 Elsevier Inc.
