In this habilitation thesis, a matrix-based approach of elimination theory is described and illustrated through applications in algebraic modeling. This matrix-based approach allows to build a bridge between geometry and numerical linear algebra, so that some geometric problems can be given to the powerful numerical linear algebra tools. The first chapter deals with matrix-based implicit representations of rational hypersurfaces in a projective space and a new method to address the computation of the intersection locus between a rational curve and a rational surface is exposed. The second chapter contains a matrix-based implicit representation of a rational curve in a projective space of arbitrary dimension. Then, the usefulness of such a r...
