Efficient Computation of Zero-Dimensional Gröbner Bases by Change of Ordering
We present an efficient algorithm for the transformation of a Grobner basis of a zero-dimensional ideal with respect to any given ordering into a GroBner basis withrespect to any other ordering. Expand

On the Theories of Triangular Sets
We study the theoretical relationship between these various approaches to triangular sets, namely characteristic set (Ritt, 1932; Wu, 1984a), regular chain and representation of a regular chain. Expand

  • 28 March 1983
In the past few years, two very different methods have been developed for solving systems of algebraic equations : the method of Gr6bner bases or standard bases [Buc I, Buc 2, Tri, P.Y] and the one which I presented in Eurosam 79 [Laz 2, Laz 3] based on gaussian elimination in some matrices. Expand

Solving parametric polynomial systems
We present a new algorithm for solving basic parametric constructible or semi-algebraic systems of the form C={x@?C^n,p"1(x)=0,...,p"s(x)=0,f"1(x) 0,...,f"l(x) 0} orExpand
