【摘要】 得到具有多个正负系数的时滞抛物型微分方程一切解振动的若干新的充分条件,推广和改进了文献[1](Kreith K,Ladas G.Allowable delays for positive diffusion processes.Hiroshi-ma Math J,1985,15:437-443)中的结果.
【Abstract】 Some new sufficient conditions for oscillation of all solutions of parabolic delay differential equtions with several positive and negative coefficients are obtained.The results extend and improve the results in the literature [1](Kreith K,Ladas G.Allowable delays for positive diffusion processes.Hiroshima Math J,1985,15:437-443).
