Fredholm operators on abelian phase spaces
Robert Fulsche, Raffael Hagger
We study the Fredholm property for linear operators on coorbit spaces over locally compact abelian phase spaces. As a special case we consider operators on , where is a…
Band-dominated and Fourier-band-dominated operators on locally compact abelian groups
Robert Fulsche, Raffael Hagger
By relating notions from quantum harmonic analysis and band-dominated operator theory, we prove that over any locally compact abelian group , the operator algebra …
Quantum harmonic analysis for polyanalytic Fock spaces
Robert Fulsche, Raffael Hagger
We develop the quantum harmonic analysis framework in the reducible setting and apply our findings to polyanalytic Fock spaces. In particular, we explain some phenomena observed in…
On the spectrum of the double-layer operator on locally-dilation-invariant Lipschitz domains
Simon N. Chandler-Wilde, Raffael Hagger, Karl-Mikael Perfekt +1
We say that , the boundary of a bounded Lipschitz domain, is locally dilation invariant if, at each , is either locally or locally coincides (in some coordinat…
Toeplitz and related operators on polyanalytic Fock spaces
Raffael Hagger
We give a characterization of compact and Fredholm operators on polyanalytic Fock spaces in terms of limit operators. As an application we obtain a generalization of the Bauer-Isra…
Toeplitz operators on the unit ball with locally integrable symbols
Raffael Hagger, Congwen Liu, Jari Taskinen +1
We study the boundedness of Toeplitz operators with locally integrable symbols on weighted harmonic Bergman spaces over the unit ball of . Generalizing earlier…
