Truncated Normal Forms for Solving Polynomial Systems: Generalized and Efficient Algorithms
Bernard Mourrain, Simon Telen, Marc Van Barel
We consider the problem of finding the isolated common roots of a set of polynomial functions defining a zero-dimensional ideal I in a ring R of polynomials over C. Normal form alg…
