摘要
本文利用一些基本不等式,对时标T上的一类二维动力方程建立了其所有解振动或收敛于0的充分条件.所得定理改进了其对应的二维常微分方程和差分方程相应的结果.最后,给出两个实例用于说明所获定理的有效性.
In this paper, some simple inequalities are applied to offer sufficient conditions for the oscillation of certain two-dimensional dynamic system on a time scale T. These results improve some known ones in the literature. Two examples indicate the effectiveness of the main results.
