Qualitative properties of Hamiltonian difference systems. (English)
[J] J. Math. Anal. Appl. 171, No.2, 334-345 (1992). ISSN 0022-247X

The authors study some qualitative properties of the Hamiltonian difference system $\Delta y(t) = B(t)y(t+1) + C(t)z(t)$, $\Delta z(t) = - A(t)y(t+1) - B\sp*(t)z(t)$, using variational and Riccati type arguments. The results further extend some of the results obtained earlier by the present authors [ibid. 167, 355-367 (1992; Zbl 0762.39003)].
