摘要
利用分析法研究一类具有强迫项的高阶差分方程Δd(a(t)x(t)-b(t)x(t-τ))+p(t)x(t-σ)+q1(t)xμ(t-σ)-q2(t)xλ(t-σ)=f(t)的振动性,得到了这类方程解振动的充分条件.
Oscillation for high-order forced difference equations △^d（a（t）x（t）-b（t）x（t-τ））＋p（t）x（t-σ）＋q1（t）x^μ（t-σ）-q2（t）xλ（t-σ）=f（t）was considered by using some analysis techniques. Some new oscillation criteria, which improved and generalized some known results in literature, were obtained.
