Oscillation, suboscillation and nonoscillation criteria for linear systems of ordinary differential equations
arXiv:2212.00310
Abstract
The Riccati equation method and an approach of the use of unknown factors is used to establish oscillation, suboscillation and nonoscillation criteria for linear systems of ordinary differential equations. A necessary condition for Lyapunov (asymptotic) stability for these systems is obtained.
