Abstract

Assume that a sequence \((A_n)_{n\in \mathbb Z}\) of bounded linear operators on a Banach space X admits a nonuniform exponential dichotomy with exponents \(\lambda >0\) and \(\epsilon \ge 0\). We formulate sufficient conditions under which a perturbed sequence \((A_n+B_n)_{n\in \mathbb Z}\) admits a nonuniform exponential dichotomy with the same exponents.

Supported in part by Croatian Science Foundation under the project IP-2019-04-1239 and by the University of Rijeka under the projects uniri-prirod-18-9 and uniri-pr-prirod-19-16.
