Lazar, A. J.; Tsui, S.-K.; Wright, S. Derivations from subalgebras of separable \(C^ *\)-algebras. (English) Zbl 0601.46057 Mich. Math. J. 31, 65-72 (1984). Let A be a separable \(C^*\)-algebra. Necessary and sufficient conditions are presented for A to have the property that all derivations defined on subalgebras of A and taking values in A are inner in the multiplier algebra of A.
