Original Abstract

The paper is concerned with a weakly delayed difference system $$x(k+1) = Ax(k) + Bx(k-1)$$ where $k = 0, 1, \dots$ and $A = (a_{ij})_{i,j=1}^{3}$, $B = (b_{ij})_{i,j=1}^{3}$ are constant matrices. It is demonstrated that the initial delayed system can be transformed into a linear system without delay and, moreover, that all the eigenvalues of the matrix of the linear terms of this system can be obtained as the union of all the eigenvalues of matrices $A$ and $B$.\\ In such a case, the new linear system without delay can be solved easily, e.g., by utilizing the well-known Putzer algorithm with one of the possible cases being considered in the paper.

Keywords

Discrete system, weak delay, initial problem, Putzer algorithm.
