Query: Computing the Walls Associated to Bridgeland Stability Conditions on
  Projective Surfaces   We derive constraints on the existence of walls for Bridgeland stability
conditions for general projective surfaces. We show that in suitable planes of
stability conditions the walls are bounded and derive conditions for when the
number of walls is globally finite. In examples, we show how to use the
explicit conditions to locate walls and sometimes to show that there are no
walls at all.
