摘要 研究以下中立型延迟微分方程 y’(t)=Ly(t)+My(t-τ1)+Ny’(t—τ2) t≥0 y(t)=g(t) t<0其中L,M,N是d×d复矩阵,τ2≥τ1>0,g(t)是给定的向量函数。证明了Runge—Kutta法是NGP-稳定的充分必要条件是它是A-稳定的。 Consider the following neutral delay differential equation (NDDE) where L, M, N are dxd complex matrixs. g(t) is a given vector function. The Runge-Kutta methods is NGP-stable if and only if it is A-stable, when used to the test system above.
