一类带脉冲的时滞差分方程的振动准则

摘要

研究了一类带有脉冲的时滞差分方程的振动性,这类差分方程的最高阶项是变系数的.将脉冲条件进行转换后,利用反证法给出了该差分方程所有解振动的一个充分条件.%The main aim of this paper is to investigate the oscillation of a type of impulsive delay difference equation whose highest order item has a coefficient of variation. A conversion of impulsive condition has been given, and a sufficient condition of the oscillation criteria of any solution has been obtained.
