Spectral theory of Hamiltonian systems with almost constant coefficients (Q618274)

The authors consider a general linear Hamiltonian irreducible system of order 2\(n\) with asymptotically constant coefficients. The coefficients satisfiy the regularity (smoothness and decay) conditions. These constraints preclude the appearance of singular continuous spectra. These results are extensions of earlier theorems of the authors. They apply these results to two-, three- and four-dimensional systems.
