ON THE OSCILLATION OF SELF-ADJOINT MATRIX HAMILTONIAN SYSTEMS
Qigui Yang, Sui Sun Cheng · Proceedings of the Edinburgh Mathematical Society · 2003
Abstract By means of monotone functionals and positive linear functionals defined on suitable matrix spaces as well as new generalized Riccati transformations, oscillation criteria for self-adjoint linear Hamiltonian matrix systems are obtained. Our results are generalizations and improvements of many existing results. AMS 2000 Mathematics subject classification: Primary 34A30; 34C10
