DESCRIPTION:We discuss the spectral theory of some Hamiltonians which aris
 e in the theory of superconductors. These operators are given by operator 
 valued two-by-two matrices which describe the evolution of both electrons 
 and holes as well as the interaction between them. We investigate the beha
 vior of the density of states of such operators as well as localization pr
 operties. This is joint work with Bernd Metzger and Peter Muller.
