Nous montrons que l’invariant de Hasse-Witt de la forme de Killing d’une algèbre de Lie semi-simple $L$ s’exprime à l’aide de l’invariant de Tits de la représentation irréductible de $L$ de poids dominant $\rho \,=\,\frac{1}{2}$ (somme des racines positives), et des invariants associés au groupe des symétries du diagramme de Dynkin de $L$.
