Abstract:
A characterization is given of those unital, 2-subhomogeneous, Fell C *-algebras which have only inner derivations. This proves Sproston and Strauss's conjecture from 1992. Various examples are given of phenomena which cannot occur for separable C *-algebras. In particular, an example is given of a C *-algebra with only inner derivations which has a quotient algebra admitting outer derivations. This answers a question of Akemann, Elliott, Pedersen and Tomiyama from 1976.
