摘要
本文讨论了线性非自治时滞微分方程 x′(t)+sum from i=1 to n p_i(t)x(t-τ_i(t))=0的解的振动性,给出所有解振动的充分条件,改进了文[1,2]的结果.
In this paper,We consider oscillation of the nonautonomous system Linear differen- tial equations with delayed arguments x'(t)+sum from i=1 to n p_i(t)x(t—τ_i(t))=0 (1) We give sufficient conditions for oscillatiot of all Solution of (1).
