Interval criteria for oscillation of linear Hamiltonian systems
New oscillation criteria are established for the linear Hamiltonian systems that are different from most known ones in the sense that they are based on the information only on a sequence of subintervals of [t(0), infinity) rather than on the whole half-line. Our results are sharper than some previous results. (C) 2004 Elsevier Ltd. All rights reserved.
