Spectrums and uniform mean ergodicity of weighted composition operators on Fock spaces (2112.05369v1)
Published 10 Dec 2021 in math.FA and math.CV
Abstract: For holomorphic pairs of symbols $(u, \psi)$, we study various structures of the weighted composition operator $ W_{(u,\psi)} f= u \cdot f(\psi)$ defined on the Fock spaces $\mathcal{F}p$. We have identified operators $W{(u,\psi)}$ that have power bounded and uniformly mean ergodic properties on the spaces. These properties are described in terms of easy to apply conditions relying on the values $|u(0)|$ and $|u(\frac{b}{1-a})|$ where $ a$ and $b$ are coefficients from linear expansion of the symbol $\psi$. The spectrum of the operators are also determined and applied further to prove results about uniform mean ergodicity.
