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…

Berezin transforms on modified Bergman spaces

Noureddine Ghiloufi, Safa Snoun

In this paper we study the continuity of the Berezin transform on modified Bergman spaces and we establish a Lipschitz estimate in terms of the Bergman-Poincaré metric.

Fractional Zernike functions

Hajar Dkhissi, Allal Ghanmi, Safa Snoun

We consider and provide an accurate study for the fractional Zernike functions on the punctured unit disc, generalizing the classical Zernike polynomials and their associated $β$ -r…
