On -trichotomy of evolution operators in Banach spaces
M. Megan, T. Ceausu, V. Crai
The paper considers some concepts of trichotomy with different growth rates for evolution operators in Banach spaces. Connections between these concepts and characterizations in te…
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…
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.
