On discrete spectra of Bergman--Toeplitz operators with harmonic symbols
Leonid Golinskii, Stanislas Kupin, Juliette Leblond +1
In the present article, we study the discrete spectrum of certain bounded Toeplitz operators with harmonic symbol on a Bergman space. Using the methods of classical perturbaton the…
Bounded Extremal Problems in Bergman and Bergman-Vekua spaces
Briceyda Delgado, Juliette Leblond
We analyze Bergman spaces A p f (D) of generalized analytic functions of solutions to the Vekua equation w = (f /f)w in the unit disc of the complex plane, for…
Solutions to inverse moment estimation problems in dimension 2, using best constrained approximation
Juliette Leblond, Elodie Pozzi
We study an inverse problem that consists in estimating the first (zero-order) moment of some R2-valued distribution m supported within a closed interval S R, from partia…
Constrained -approximation by polynomials on subsets of the circle
L Baratchart, Juliette Leblond, Fabien Seyfert
We study best approximation to a given function, in the least square sense on a subset of the unit circle, by polynomials of given degree which are pointwise bounded on the complem…
Constrained optimization in classes of analytic functions with prescribed pointwise values
Laurent Baratchart, Juliette Leblond, Dmitry Ponomarev
We consider an overdetermined problem for Laplace equation on a disk with partial boundary data where additional pointwise data inside the disk have to be taken into account. After…
Composition operators on generalized Hardy spaces
Sam Elliott, Juliette Leblond, Elodie Pozzi +1
Let be bounded domains. Let holomorphic in and belonging to . We study the composition operators…
