Exponential Instability of Skew-evolution Semiflows in Banach Spaces

A Note on Power Instability of Linear Discrete-time Systems in Banach Spaces

“…Other results, concerning nonuniform exponential stability concepts have been studied by L. Barreira and C. Valls in [2]. Diverse and important concepts of instability have been introduced and studied (see [9] for semigroups of operators, [10], [11] for evolution operators, [8] for linear skew-product flows).…”
