Closable derivations of simple C*-algebras
Published online by Cambridge University Press: 18 May 2009
Extract
In this note we show that any derivation of a simple C*-algebra, whose range is not dense, is closable. We also derive a necessary and sufficient condition for a *-derivation of a C*-algebra, which is defined on the domain of a closed *- derivation, to be closed.
