1. Oscillation of nonlinear three-dimensional difference systems with delays Creator: Schmeidel, Ewa Format: bez média and svazek Type: model:article and TEXT Subject: difference equation, three-dimensional nonlinear system, and oscillation Language: English Description: In this paper the three-dimensional nonlinear difference system ∆xn = anf(yn−l ), ∆yn = bng(zn−m), ∆zn = δcnh(xn−k), is investigated. Sufficient conditions under which the system is oscillatory or almost oscillatory are presented. Rights: http://creativecommons.org/publicdomain/mark/1.0/ and policy:public
