B. Aulbach et al., THE CONCEPT OF SPECTRAL DICHOTOMY FOR LINEAR DIFFERENCE-EQUATIONS, Journal of mathematical analysis and applications, 185(2), 1994, pp. 275-287
This paper is concerned with two notions of dichotomies for linear dif
ference equations in Banach spaces. We introduce the new concept of sp
ectral dichotomy and relate it to the known notion of exponential dich
otomy. The equations we consider are in general not supposed to have i
nvertible right-hand sides. (C) 1994 Academic Press, Inc.
