IDENTIFYING PERTURBATIONS WHICH PRESERVE ASYMPTOTIC STABILITY.
Abstract
Let the zero solution be uniform-asymptotically stable for x' = f(t,x). Estimates are established in terms of the rate of approach to zero of the solutions of x' = f(t,x), on the magnitude of g(t,x) in order that the zero solution be uniform-asymptotically stable for x' = f(t,x) + g(t,x). A new proof and slight extension of Hahn's theorem is given, using these estimates. If f is homogeneous of degree k, then uniform-asymptotic stability is preserved by g(t,x) = o(/x/superscript k).
