Abstract
English
We investigate the Zariski closure of the projective equivalence class of a matrix. New results are presented regarding the matrices in this variety and their matroids, and we give equations for the variety. We also discuss the K-polynomial of the closure of a projective equivalence class, and two other geometric invariants that can be obtained from this.

Nous enquêtons sur l'adhèrence Zariski de la classe d'équivalence projective d'une matrice. Des rèsultats nouveaux sont prèsentès sur les matrices dans cette variètè et leur matroï des, et nous donnons èquations pour la variètè. Nous discutons ègalement le K-polynôme de l'adhèrence de la classe d'èquivalence projective, et deux autres invariants gèomètriques qui peuvent être obtenus à partir de cela.
