Finite sums of commutators in C * -algebras
Annales de l'Institut Fourier, Tome 32 (1982) no. 1, pp. 129-137

We prove that for many C * -algebras, the null space of all finite traces is spanned by finite sums of commutators.

Nous montrons que, pour certaines C * -algèbres, le noyau de toutes les traces finies est engendré par des sommes finies de commutateurs.
