| Abstract: We adapt the notion of spectral synthesis, originally introduced into operator theory by John Wermer, to show that on any Hilbert space of holomorphic functions for which all point eval-uation functionals are continuous, the collection of nonscalar adjoint multiplication op-erators has a common cyclic vector. Our work extends previous results of Warren Wogen and K.C. Chan to their most natural setting. Our methods also produce common cyclic vectors for the collection non-scalar "translation-invariant" operators on the Fréchet space of entire functions, this generalizing another theorem of Chan. |
