Les formes bilinéaires et quadratiques bonnes de hauteur 2 en caractéristique 2

Abstract

Our aim is to give a complete classification of bilinear and quadratic forms which are good of height 2 over a field of characteristic 2, i.e., those whose anisotropic parts over their function fields are similar to bilinear Pfister forms which are definable over the ground field. We include other related results.
