Spectral properties of commutators on harmonic Bergman spaces of the unit disk

Khaled Chbichib, Noureddine Ghiloufi

In this paper, we determine the asymptotic behavior of the singular values of the commutator $C_{u} := [M_{u}, P_{α}]$ acting on $L^{2} (D, d A_{α})$ , where $M_{u}$ is…

Spectral properties of the Cauchy transform on modified Bergman spaces

Khaled Chbichib, Noureddine Ghiloufi, Safa Snoun

In this paper, we determine the singular values $s_{n} (T_{α, β})$ and $s_{n} (R_{α, β})$ of the operators $T_{α, β} = C P_{α, β}$ and $R_{α,β}=\mathbb P_{α,β}\mathcal C\mathbb…
