The Habicht Approach to Subresultants
Chung-Jen Ho, Chee Keng Yap · Journal of Symbolic Computation · 1996
The Habicht approach to the theory of subresultants is based on studying polynomial remainder sequences (PRS) with indeterminate coefficients, and predicting the effects of specializing these coefficients. This has advantages as noted by Loos. We give a complete treatment of this approach by introducing the concept of pseudo-subresultants.
