SUMMARY:Low energy spectral and scattering theory for relativistic Schroed
 inger operators - Umeda\, T (University of Hyogo)
DTSTART:20120801T100000Z
DTEND:20120801T104500Z
UID:TALK39133@talks.cam.ac.uk
CONTACT:Mustapha Amrani
DESCRIPTION:We shall report some recent progress on spectral and scatterin
 g theory at low energy for the relativistic Schroedinger operators in the 
 massless case. Some striking properties of the operator will be exhibited:
  (1) the absence of the zero-energy resonances\; (2) the zero energy is no
 t an accumulation point of embedded eigenvalues of the operator if 0 is no
 t an eigenvalue. Low energy behavior of the wave operators and of the scat
 tering operator will be presented. (This talk is based on joint work with 
 Serge Richard.) \n\n
