摘要
We show that if the Lyapunov exponents of a linear difference equation x(m + 1) = L(m)x(m) are limits, then the same happens with the Lyapunov exponents of the solutions of the nonlinear equation x (m + 1) = L(m)x(m) + f(m)(x(m)) for any sufficiently small sequence fm. We consider the general case of infinite delay. (C) 2011 Elsevier Masson SAS. All rights reserved.
