Résumé

Let $E = E (0, \infty)$ be a symmetric function space and $E (ℳ, τ)$ be the noncommutative symmetric space corresponding to $E (0, \infty)$ associated with a von Neumann algebra with a faithful normal semifinite trace. Our main result identifies the class of spaces $E$ for which every derivation $δ : 𝒜 \to E (ℳ, τ)$ is necessarily inner for each $C^{*}$ -subalgebra $𝒜$ in the class of all semifinite von Neumann algebras $ℳ$ as those with the Levi property.
