【摘要】 研究延迟微分方程y′(t)=ay(t)+by(qt);0<q<1,a,b∈c的数值解法的渐近稳定性,给出了数值解稳定的充分条件及必要条件,解决了部分A,Iserles在文献[1]中提出的猜想.
【Abstract】 We study the asymptotic stability of the numerical solution of pantograph delay differential equations in the form of y′(t)=ay(t)+by(qt) 0<q<1, a,b∈c. and give the sufficient and necessary conditions for the numerical stability and solve in part the A.Iserles’ conjecture in reference .
