Abstract

The aim of the paper "Discrete Lyapunov theory for evolution families" is to obtain some necessary and sufficient conditions for uniform exponential dichotomy, in the discrete case for  C_0-semigroups, differential systems and abstract evolution families in Hilbert spaces. We prove firstly the discrete versions of some theorems from the continuous case from P. Preda, M. Megan, Exponential dichotomy of strongly discontinuous semigroups, Bull. Austral. Math. Soc. 30(1984), 435-448, P. Preda, M. Megan, Exponential Dichotomy of Evolutionary Processes in Banach Spaces, Czechoslovak Math. J. 35(1985), 312-323 and we use them to obtain the results of Lyapunov type.
