Query: Explicit Description of A Certain Destabilizing Wall of Skyscraper
  Sheaves on Ruled Surfaces   We give a explicit description of gluing stability conditions on ruled
surfaces by introducing gluing perversity. Moreover, we describe a
destabilizing wall of skyscraper sheaves on ruled surfaces by deformation of
stability conditions glued from $\widetilde{GL^{+}}(2,\mathbb{R})$-translates
of the standard stability condition on the base curve.
