Oscillatory properties of solutions of three-dimensional difference systems. (English) Zbl 1086.39014
The authors obtain some oscillation criteria for the difference system \[ \begin{aligned} \Delta x_n&=a_ny_n^\alpha,\\ \Delta y_n &=b_nz_n^\beta,\\ \Delta z_n&=-c_nx_n^\gamma. \end{aligned} \] Examples are also included.
