The Douglas question on the Bergman and Fock spaces

Jian-hua Chen, Qianrui Leng, Xianfeng Zhao

Let $μ$ be a positive Borel measure and $T_{μ}$ be the bounded Toeplitz operator induced by $μ$ on the Bergman or Fock space. In this paper, we mainly investigate the invertibility o…

Toeplitz operators on $L^{p}$ -spaces of a tree

Mingmei Huang, Xiaoyan Zhang, Xianfeng Zhao

Let $T$ be a rooted, countable infinite tree without terminal vertices. In the present paper, we characterize the spectra, self-adjointness and positivity of Toeplitz operators on…
