SUMMARY: (...): From Crystal Optics to Dirac Operators:   a Spectral Theory
  of First-Order Systems
DESCRIPTION:: First-order systems of partial differential equationsappear i
 n many areas of physics\, from the Maxwell equations to the Diracoperator.
     The aim of the talk is to describe a general method for the study ofth
 e spectral density of all such systems\, connecting it to traces on the (g
 eometric-optical)  "slowness surfaces" .    The Holder continuity of the s
 pectral density leads to a derivationof the limiting absorption principle 
 and global spacetime estimates.  (based on joint work with Tomio Umeda).[h
