OSCILLATION OF NEUTRAL DIFFERENTIAL EQUATIONS WITH CONTINUOUS DELAY
【摘要】 讨论下列一阶具连续时滞中立型微分方程[x(t) - ∫τ0 p(s)x(t -s)ds]′+∫σ0 q(s)x(t -s)ds=0获得了该方程所有解振动的充分必要条件。
【Abstract】 The first order neutral differential equations with continuous delay resembling [x(t)-∫ τ 0p(s)x(t-s)ds]′+∫ σ 0q(s)x(t-s)ds=0 is discussed.Its necessary and sufficient conditon for the oscillation of every solution of this equation is obtained.
