Abstract
Let A be a subalgebra with the unit operator I in B(H), we say that a linear mapping Ï from A into B(H) is a generalized derivable mapping at zero point if Ï(ST) = Ï(S)T + SÏ(T) â SÏ(I)T for any S, TâA with ST = 0. In this paper, we show the following main result: every norm-continuous generalized derivable mapping at zero point on finite CSL algebras is a generalized derivation.
