摘要
在文[4]的基础上,采用新方法重新获得了滞后型方程x(t)+ax(t)+bx(t-τ)=0零解渐近稳定充要条件的代数判据。(其中a、b任意常数,τ为正常数。)
Base on paper [4], the author obtains algebra criterion. which is sufficient and necessary conditions of zero solution asymptotic stability, for the delay differential equation x(t) + ax(t) + b x(t -) =0 where a, b, >0 are arbitrary real constants.
