Abstract

 First-order systems of partial differential equations appear
in many areas of physics, from the Maxwell equations to the Dirac
operator.
    The aim of the talk is to describe a general method for the study of
the spectral density of all such systems, connecting it to traces on the
(geometric-optical)  "slowness surfaces" .
    The Holder continuity of the spectral density leads to a derivation of
the limiting absorption principle and global spacetime estimates
  (based on joint work with Tomio Umeda).
