摘要:
We prove a microlocal partition of energy for solutions to linear half-wave or Schrodinger equations in any space dimension. This extends well-known (local) results valid for the wave equation outside the wave cone, and allows us in particular, in the case of even dimension, to generalize the radial estimates due to Cote, Kenig and Schlag to nonradial initial data.
