Original Abstract

In the paper we consider two-dimensional linear non-homogeneous system of discrete equations y_1(k + 1) = py_1(k) + qy_2(k) + g_1(k), y_2(k + 1) = −qy_1(k) + py_2(k) + g_2(k), where k = a, a + 1, . . . with a fixed integer a ∈ N, p, q are real constants, g_i {a, a + 1, . . . } → R, i = 1, 2 are given functions. Sufficient conditions are derived guaranteeing the existence of a solution y(k) = (y_1(k), y_2(k)), k = a, a + 1, . . . satisfying y_1^2(k) + y_2^2(k) < M, where M is a given positive constant.

Keywords
