Stability in n-dimensional delay differential equations ✩

In this paper, we give some sufficient conditions for the zero solution of an n-dimensional delay differential equation of the form ˙x(t) = A(t)x t − τ(t,xt ) , t 0, to be uniformly stable and asymptotically stable. These conditions extend and improve the existing relative results in literature.  2004 Elsevier Inc. All rights reserved
