Norm bounds for self-adjoint Toeplitz operators with non-radial symbols on the Fock space

In this paper we extend Galbis’ elegant norm bounds for self-adjoint Toeplitz operators on the Fock space to bounded and integrable symbols which are non-radial. The main ingredients are a transplantation of the remarkable Nicola-Tilli isoperimetric inequality to the realm of Fock-Toeplitz operator theory and a two-dimensional adaption of Galbis’ integration and approximation arguments.
