Gröbner duality and multiplicities in polynomial system solving
Maria Grazia Marinari, Teo Mora, Hans Michael Möller · 1995
This paper deals with the description of the solutions of zero dimensional systems of polynomial equations.Based on different models for describing solutions, we consider suitable representations of a multiple root, or more precisely suitable descriptions of the primary component of the system at a root.We analyse the complexity of finding the representations.We also discuss the current approach to the representation of real roots,
