| Research Abstract |
Dynamical systems which appear in numerical simulation are often described by differential-algebraic equations(DAEs). In order to improve accuracy of numerical simulation, a great deal of research has been made on numerical solution methods. However, accuracy depends not only on how to solve but also on what to solve. This research has developed methods to obtain DAEs which are easy to solve numerically.
