Qısa məlumat

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.
