Weak dispersion for the Dirac equation on asymptotically flat and warped   products spaces
  We prove local smoothing estimates for the Dirac equation on some non-flat manifolds; in particular, we will consider asymptotically flat and warped products metrics. The strategy of the proofs relies on the multiplier method.
