On stability of generalised systems of difference equation with non-consistent initial conditions
Nicholas Apostolopoulos, Fernando Ortega, Grigoris Kalogeropoulos
For given non-consistent initial conditions, we study the stability of a class of generalised linear systems of difference equations with constant coefficients and taking into acco…
A boundary value problem of a generalised linear discrete time system with no solutions and infinitely many solutions
Nicholas Apostolopoulos, Fernando Ortega, Grigoris Kalogeropoulos
In this article we study a class of generalised linear systems of difference equations with given boundary conditions and assume that the boundary value problem is non-consistent,…
The case of a generalised linear discrete time system with infinite many solutions
Nicholas Apostolopoulos, Fernando Ortega, Grigoris Kalogeropoulos
In this article we study a class of generalised linear systems of difference equations with given non-consistent initial conditions and infinite many solutions. We take into consid…
Solutions of Higher Order Homogeneous Linear Matrix Differential Equations: Singular Case
Grigoris Kalogeropoulos, Charalambos Kontzalis
The main objective of this talk is to develop a matrix pencil approach for the study of an initial value problem of a class of singular linear matrix differential equations whose c…
A note on the relation between a singular linear discrete time system and a singular linear system of fractional nabla difference equations
Charalambos P. Kontzalis, Grigoris Kalogeropoulos
In this article we focus our attention on the relation between a singular linear discrete time system and a singular linear system of fractional nabla difference equations whose co…
