Magnetic Fields,r is positive in some sense. The ideas in this chapter can be traced back to . , . and . for theorems on the absence of singular spectrum, and to . and . for theorems on absence of positive eigenvalues.

Random Jacobi Matrices,erve in solid state physics as models of disorded systems, such as alloys, glasses and amorphous materials. The disorder of the system is reflected by the dependence of the potential on some random parameters.

Almost Periodic Jacobi Matrices,timately connected. Almost periodic Jacobi matrices, as well astheir continuous counterparts, have been the subjects of intensive research in the last years. They show surprising phenomena such as singular continouous spectrum. pure point spectrum and absolutely continuous spectrum that is nowhere dense!

Complex Scaling,Complex scaling, also known as the method of complex coordinates, coordinate rotation or dilation analyticity, has developed rapidly in the last fifteen years(see(8)and the references there), and has become a powerful tool in numerical studies of resonances.
