Toeplitz operators in polyanalytic bergman type spaces
Kapitel i bok, 2019
We consider Toeplitz operators in Bergman and Fock type spaces of polyanalytic L2-functions on the disk or on the half-plane with respect to the Lebesgue measure (resp., on C with the plane Gaussian measure). The structure involving creation and annihilation operators, similar to the classical one present for the Landau Hamiltonian, enables us to reduce Toeplitz operators in true polyanalytic spaces to the ones in the usual Bergman type spaces, however with distributional symbols. This reduction leads to describing a number of properties of the operators in the title, which may differ from the properties of the usual Bergman-Toeplitz operators.
