Oscillation of nonlinear three-dimensional difference systems with delays

Ewa Schmeidel (2010)

Mathematica Bohemica

Similarity:

In this paper the three-dimensional nonlinear difference system Δ x n = a n f ( y n - l ) , Δ y n = b n g ( z n - m ) , Δ z n = δ c n h ( x n - k ) , is investigated. Sufficient conditions under which the system is oscillatory or almost oscillatory are presented.
