چکیده
This paper deals with two concepts of polynomial dichotomy for linear difference equations which are defined in a Banach space and whose norms can increase not faster than exponentially. Some illustrating examples clarify the relations between these concepts. Our approach is based on the extension of techniques for exponential dichotomy to the case of polynomial dichotomy. The obtained results are generalizations of well-known theorems about the exponential stability and exponential dichotomy.

ON h − TRICHOTOMY OF LINEAR DISCRETE - TIME SYSTEMS IN BANACH SPACES
The aim of this paper is to give characterizations of a general concept of trichotomy of time-varying linear systems described by difference equations with noninvertible operators in Banach spaces. This concept contains as particular cases the classical properties of (uniform and nonuniform) exponential trichotomy and polynomial trichotomy. The approach is motivated by two examples. 2000 Mathem...
متن کاملPairs of Function Spaces and Exponential Dichotomy on the Real Line
We provide a complete diagram of the relation between the admissibility of pairs of Banach function spaces and the exponential dichotomy of evolution families on the real line. We prove that if W ∈ H R and V ∈ T R are two Banach function spaces with the property that either W ∈ W R or V ∈ V R , then the admissibility of the pair W R, X , V R, X implies the existence of the exponential dichotomy...
متن کاملOn the Robustness of Exponential Dichotomies
For linear evolution families in Banach spaces, we establish the robustness of a weaker notion of exponential dichotomy. This notion allows the contraction and expansion along the stable and unstable subspaces to be nonuniform and requires nothing from the angles between these subspaces.
متن کاملExponential Dichotomy and Trichotomy for Skew-Evolution Semiflows in Banach Spaces
The paper emphasizes the properties of exponential dichotomy and exponential trichotomy for skew-evolution semiflows in Banach spaces, by means of evolution semiflows and evolution cocycles. The approach is from uniform point of view. Some characterizations which generalize classic results are also provided. Mathematics Subject Classification: 34D09

For an evolution family on the half-line U = (U(t; s)) ts0 of bounded linear operators on a Banach space X we introduce operators G 0 ; G X and I X on certain spaces of X-valued continuous functions connected with the integral equation u(t) = U(t; s)u(s) + R t s U(t;)f()dd: We characterize exponential stability, exponential expansiveness and exponential dichotomy of U by properties of G 0 ; G X...
