Abstract:
The classical criterion of asymptotic stability of the zero solution of equations x′ = f (t, x) is that there exists a function V (t, x), a ({norm of matrix} x {norm of matrix}) ≤ V (t, x) ≤ b ({norm of matrix} x {norm of matrix}) for some a, b ∈ K, such that over(V, ̇) (t, x) ≤ - c ({norm of matrix} x {norm of matrix}) for some c ∈ K. In this paper we prove that if f (t, x) is bounded, over(V, ̇) (t, x) is uniformly continuous and bounded, then the condition that over(V, ̇) (t, x) ≤ - c ({norm of matrix} x {norm of matrix}) can be weakened and replaced by over(V, ̇) (t, x) ≤ 0 and {(t, x) : x ≠ 0, over(over(V, ̄), ̇) (t, x) = 0} contains no complete trajectory of x′ = over(f, ̄) (t, x), t ∈ [- T, T], where over(V, ̄) (t, x) = limk → ∞ V (t + tk, x), over(f, ̄) (t, x) = limk → ∞ f (t + tk, x) uniformly for (t, x) ∈ [- T, T] × BH. © 2006 Elsevier Inc.
