Inversion of parameterized hypersurfaces by means of subresultants

L. Buse, C. D'Andrea

 

We present a subresultant-based algorithm for deciding if the parametrization of a toric hypersurface is invertible or not, and for computing the inverse of the parametrization in the case where it exists. The algorithm takes into account the monomial structure of the input polynomials.
