强迫项正负系数中立型时滞差分方程的振动性
Oscillation of forced neutral several delay differential equations with positive and negative coefficients
摘要
Abstract
This study investigates the oscillation of forced neutral delay differential equations with positive andnegative coefficients problem. The criteria for determining the existence of the bounded eventually positivesolution is obtained by using the appropriate inequality and reduction to absurdity. Moreover, two sufficientconditions for oscillatory of the equation are given. This study improves and extends the understanding in thefield.关键词
