Query: Weighted Energy Decay for 3D Klein-Gordon Equation   We obtain a dispersive long-time decay in weighted energy norms for solutions
of the 3D Klein-Gordon equation with generic potential. The decay extends the
results obtained by Jensen and Kato for the 3D Schredinger equation. For the
proof we modify the spectral approach of Jensen and Kato to make it applicable
to relativistic equations.
