On nonuniform exponential dichotomy of evolution operators in Banach spaces.
(English)
[J] Integral Equations Oper. Theory 44, No. 1, 71-78 (2002). ISSN 0378-620X; ISSN 1420-8989/e

The authors study the nonuniform exponential dichotomy of evolution operators in Banach spaces. It is shown that $(C_0,C_0)$-admissibility for evolution operators implies nonuniformly exponentially dichotomy, and that the converse generally does not as an example shows. This paper is related to the paper of {\it Nguyen Van Minh, F. Räbiger} and {\it R. Schnaubelt} [Integral Equations Oper. Theory 32, 332--353 (1998; Zbl 0977.34056)], which discussed the uniform case.
