Weighted energy decay for magnetic Klein-Gordon equation
Alexander Komech, Elena Kopylova
We obtain a dispersive long-time decay in weighted energy norms for solutions of 3D Klein-Gordon equation with magnetic and scalar potentials. The decay extends the results obtaine…

On eigenfunction expansion of solutions to the Hamilton equations
Alexander Komech, Elena Kopylova
We establish a spectral representation for solutions to linear Hamilton equations with positive definite energy in a Hilbert space. Our approach is a special version of M. Krein's…
