Let A be a subalgebra with the unit operator I in B(H ), we say that a linear mapping ϕ from A into B(H ) is a generalized derivable mapping at zero point if ϕ(ST ) = ϕ(S)T + Sϕ(T ) -Sϕ(I )T for any S, T ∈ A with ST = 0. In this paper, we show the following main result: every norm-continuous general
