中文摘要 | 一些有關於具有延遲性之二階中立型微分方程 [a(t)(x(t)+p(t)x(t-r))1]1+q(t)f(x(t-σ))=0,振動判別的建立,其中r和σ是非負的常數,且,a,p,qεC(t0,∞); R),fεC(R;R)。這些判別改良並擴充了一些具有延遲性和中立型微分方程之著名結論。 |
英文摘要 | Some oscillation criteria are given for the second order neutral delay differential equation [a(t)(x(t)+p(t)x(t-r))1]1+q(t)f(x(t-σ))=0, were r andσ are nonnegative constants ,a,p,qεC(t0,∞); R)and fεC(R;R). These results generalize and improve some known results about both neutral and delay differential equations. |
