Abstract:Let $ Omega$ be an open connected subset of the plane, and let $ A$ be a Banach algebra of analytic functions on $ Omega$. We show that the space of bounded derivations from $ A$ into $ A^*$ is not reflexive. We also obtain similar results when $ A=C^{(n)}[0,1]$ for $ ngeq 2$.

Keywords:Local derivations   reflexivity   analytic functions   differentiable functions
