Oscillations of delay difference systems. (English) Zbl 0913.39007
For the difference system $x(t)= \sum^p_{j=1} A_j(t) x(t-r_j)$ in $\bbfR^n$ with positive, pairwise different $r_j$, the oscillatory behaviour of the components of the solutions is investigated. Some special results concern the autonomous resp. the scalar case.
