Abstract: |
This paper is concerned with the asymptotic stability of numerical methods applied to linear differential-algebraic equations. The coefficient matrices of the system are constant rectangular matrices. We consider linear multistep methods and Runge-Kutta methods applied to the system. The stability results are established under Kronecker canonical form of the original system. |
