Differential transform method applied to high index differential-algebraic equations. (English) Zbl 1115.65089
Summary: F. Ayaz [Appl. Math. Comput. 152, No. 3, 649–657 (2004; Zbl 1077.65088)] had considered the numerical solution of linear differential-algebraic equations (DAEs) by the differential transform method. Two index-1 DAEs have been solved by using the method and the numerical solutions coincide with the exact solution very well.
In this paper, high index DAEs are considered. Index-2 DAEs can be done in a similar way. A counter example is proposed to explain that the method is not suitable for all index-3 DAEs.
