Jl. Hong et al., EXPONENTIAL DICHOTOMIES, ALMOST-PERIODIC STRUCTURALLY STABLE DIFFERENTIAL-SYSTEMS, AND AN EXAMPLE, Journal of mathematical analysis and applications, 208(1), 1997, pp. 71-84
In this paper, we introduce concepts of almost periodic topological (i
n short, APT) equivalence and almost periodic structural (in short, AP
S) stability of differential systems, and a necessary and sufficient c
ondition for APS stability of differential systems. Furthermore, we di
scuss the inheritability of the APS stability and density of APS stabl
e differential systems in a certain space of uniformly almost periodic
differential systems. (C) 1997 Academic Press.
