The approximate regularization of index-2 differential-algebraic problems

[摘要] The approximate regularization method is introduced for the solution of index-2 Hessenberg systems of differential-algebraic equations. This approach is based on using a Taylor-series-type method, which results in a singular perturbation ordinary differential systems. For linear problems, it is shown that this approach is stable. To compare with a partial regularization, the approximate regularization appears to be promising.
