Research Article: “Delayed linear difference equations: the method of Z-transform" - Electronic Journal of Qualitative Theory of Differential Equations — October 2020

Author: Prof. Dr. NAZIM MAHMUDOV

"A system of nonhomogeneous linear difference equations with linear parts given by non-commutative matrices is studied. Representation of its solution is de- rived by means of newly defined delayed perturbation of discrete matrix exponential using the Z-transform. We discard the invertibility condition of matrix of non delayed term used in recent works related to the representation of solutions for delayed linear difference systems.”
