Examples of Differential Systems with Contrasting Combinations of Radial Stability and Instability
摘要
Abstract
Using specific examples, the paper proves that the presence of radial stability, asymptotic stability, or complete instability (of any type: Lyapunov, Perron, or upper-limit) properties of a non-one-dimensional autonomous nonlinear differential system, along each ray starting from zero, generally speaking, does not imply the presence of stability, asymptotic stability, or, accordingly, complete instability of the same type.
