Query: Global W^1,p regularity for an elliptic problem with measure source and
  Leray-Hardy potential,   In this paper, we develop the Littman-Stampacchia-Weinberger duality approach
to obtain global W^1,p estimates for a class of elliptic problems involving
Leray-Hardy operators and measure sources in a distributional framework
associated with a dual formulation with a specific weight function.
