Correspondence theory on -Fock spaces with applications to Toeplitz algebras
Robert Fulsche
We prove several results concerning the theory of Toeplitz algebras over -Fock spaces using a correspondence theory of translation invariant symbol and operator spaces. The most…
Berger-Coburn theorem, localized operators, and the Toeplitz algebra
Wolfram Bauer, Robert Fulsche
We give a simplified proof of the Berger-Coburn theorem on the boundedness of Toeplitz operators and extend this theorem to the setting of -Fock spaces .…
Toeplitz operators on pluriharmonic function spaces: Deformation quantization and spectral theory
Robert Fulsche
Quantization and spectral properties of Toeplitz operators acting on spaces of pluriharmonic functions over bounded symmetric domains and are discussed. Results are p…
Approximation of eigenvalues of Schrödinger operators
Johannes F. Brasche, Robert Fulsche
It is known that convergence of l.s.b. closed symmetric sesquilinear forms implies norm resolvent convergence of the associated self-adjoint operators and this in turn convergence…
