摘 要:研究具有脈沖的多時(shí)滯差分方程,通過構(gòu)造輔助函數(shù),借助于反證法、單調(diào)有界原理及函數(shù)的連續(xù)性,得到了方程振動(dòng)的兩個(gè)充分條件,將某些結(jié)論在脈沖和多時(shí)滯的條件下進(jìn)行改進(jìn)和推廣,使其應(yīng)用更加廣泛.

關(guān)鍵詞:連續(xù)變量;脈沖時(shí)滯差分方程;振動(dòng)性

Abstract:In this paper,it is considered that the impulsive several delays difference equation, It is used the method of constructing auxiliary function, With the help of the absurdity、monotone of Function, the two sufficient conditions are obtained for ocillation of all solutions and some results of impulsive and several delays are improved and promoted. The results are more widely available.

Key words:continuous arguments;impulsive delay difference equation;oscillation
