Sums of commutators in ideals and modules of type II factors
Annales de l'Institut Fourier, Volume 55 (2005) no. 3, p. 931-971
Let be a factor of type II or II 1 having separable predual and let ¯ be the algebra of affiliated τ-measurable operators. We characterize the commutator space [,𝒥] for sub-(,)- bimodules and 𝒥 of ¯.
Soit un facteur de type II ou II 1 avec prédual séparable et soit ¯ l’algèbre d’operateurs τ-mesurable et affilié avec . Nous caractérisons l’espace des sommes de commutateurs [,𝒥] pour tous sous-(,)-bimodules et 𝒥 de ¯.
