摘要
建立线性时滞微分方程x (t) +∑ni=1 pi(t) x(t- τi(t) ) =0 , t≥ to的所有解振动的新准则。当 pi(t) ,τi(t) (i=1 ,2 ,… ,n)均为常数时 ,条件是充分必要的。
The aim of this paper is to study the oscillation for the linear delay differential equation, x(t)+∑ni=1p_i(t)x(t-τ_i(t))=0. Some new criterions are obtained for the oscillation of all solutions for the above equation. These conditions improve and extend some known results.
