Abstract

We present a method based on symbolic-numeric reduction to geometric involutive form to compute the primary component and the differential operators f solution of a polynomial ideal. The singular solution can be exact or approximate. If the singular solution is known with limited accuracy, then we propose a new method to refine it to high accuracy.
