摘要
研究了如下具有连续变量的脉冲时滞差分方程x(t)-x(t-τ)+∑i=1 m pi(t)x(t-σi)=0,t≥0, t≠tk x(t+k)-x(tk)=bkx(tk),k=1,2,…通过构造辅助函数,得到了方程解振动的两个充分条件,推广和改进了已有文献中的某些结果.
The following impulsive delay difference equation with continuous arguments is considered x(t)-x(t-τ)+∑ i=1 m pi(t)x(t-σi)=0,t≥0,t≠tk x(tk+)-x(tk)=bkx(tk),k=1,2,… By constructing the auxiliary functions,the two sufficient conditions for oscillation of the solutions are obtained and some results in the literatures are improved and extended.
