Exponential Splitting for Nonautonomous Linear Discrete-Time Systems in Banach Spaces
Mihail Megan, Ioan-Lucian Popa
In this paper we consider some concepts of exponential splitting for nonautonomous linear discrete-time systems. These concepts are generalizations of some well-known concepts of (…
Characterizations of the Trichotomy for Linear Time-Varying Systems
Ioan-Lucian Popa, Traian Ceauşu, Mihail Megan
The present paper considers a concept of trichotomy for noninvertible linear time-varying systems in Hilbert spaces. This work provides a characterization for linear ti…
Nonuniform power instability and Lyapunov sequences
Ioan-Lucian Popa, Traian Ceausu, Mihail Megan
The aim of this paper is to present necessary and sufficient conditions for nonuniform power instability property of linear discrete-time systems in Banach spaces. A characterizati…
A note on power instability of linear discrete-time systems in Banach spaces
Ioan-Lucian Popa
In this paper we investigate the power instability properties and give necessary and sufficient conditions for the concepts of uniform power instability, power instability and stro…
On exponential stability for linear discrete-time systems in Banach spaces
Ioan-Lucian Popa, Traian Ceausu, Mihail Megan
In this paper we investigate four concepts of exponential stability for difference equations in Banach spaces. Characterizations of these concepts are given. They can be considered…
Exponential dichotomies for linear discrete-time systems in Banach spaces
Ioan-Lucian Popa, Mihail Megan, Traian Ceausu
In this paper we investigate some dichotomy concepts for linear difference equations in Banach spaces. We motivate our approach by illustrative examples.
