Query: Nonlocal Lazer-McKenna type problem perturbed by the Hardy's potential
  and its parabolic equivalence   In this paper, we study the effect of Hardy potential on the existence or
non-existence of solutions to a fractional Laplacian problem involving a
singular nonlinearity. Also, we mention a stability result.
