Bergman Projections, Kernel -Norm Estimates, and Toeplitz Operators with Békollé and Bonami weights

Hicham Arroussi, Jari Taskinen, Cezhong Tong +1

In this paper, we establish entirely new -norm estimates for reproducing kernels to characterize the bounded and compact Toeplitz operators acting between weighted Békol…

Homogenization and operator estimates for Steklov problems in perforated domains

Andrii Khrabustovskyi, Jari Taskinen

Let the set be obtained from the bounded domain by removing a family of -periodically distributed identical balls. In one consid…

On parameter-dependent inhomogeneous boundary-value problems in Sobolev spaces

Olena Atlasiuk, Vladimir Mikhailets, Jari Taskinen

We study a wide class of linear inhomogeneous boundary-value problems for th order ODE-systems depending on a parameter belonging to a general metric space . Th…

Elliptic functions, Floquet transform and Bergman spaces on doubly periodic domains

Jari Taskinen, Zhan Zhang

We study Bergman spaces A^2(D), their kernels and Toeplitz operators on unbounded, doubly periodic domains D in the complex plane. We establish the mapping properties of the Floque…

Parameter-dependent inhomogeneous boundary-value problems in Sobolev spaces

Olena Atlasiuk, Vladimir Mikhailets, Jari Taskinen

We study a wide class of linear inhomogeneous boundary-value problems for th order ODE-systems depending on a parameter in a general metric space . The solution…

Quasiconformal symbols and projected composition operators

Sinem Sönmez, Jari Taskinen

We study projected composition operators K_g with quasiconformal symbols g on weighted Bergman spaces on the open unit disc D. If the symbol were conformal, i.e.a Möbius transform…
