چکیده
We obtain a noncommutative multivariable analogue of Louhichi and Olofsson characterization Toeplitz operators with harmonic symbols on the weighted Bergman space $A_m({\bf D})$, as well Eschmeier Langendorfer extension to unit ball ${\bf C}^n$. All our results are proved in more general setting poly-hyperballs D_n^m}(H)$, n,m}\in {\bf N}^k$, used characterize bounded free $k$-pluriharmonic functions operator coefficients solve associated Dirichlet problem. In particular, hold for reproducing kernel Hilbert $$ \kappa_{\bf m}(z,w):=\prod_{i=1}^k \frac{1}{(1-\bar z_i w_i)^{m_i}},\qquad z,w\in D}^k, where $m_i\geq 1$. This includes Hardy space, over polydisk.

Properties of Iteration of Toeplitz Operators with Toeplitz
We consider the problems of preconditioning and iterative inversion of Toeplitz operators on sequences of complex numbers. We divide the preconditioned operator into two parts, of which one is compact and the other is regarded as a small perturbation. It will be shown that the Krylov subspace methods (such as GMRES) will perform initially at superlinear speed when applied to such preconditioned...

متن کاملToeplitz Operators and Toeplitz Algebra with Symbols of Vanishing Oscillation
We study the C∗-algebra generated by Teoplitz operators with symbols of vanishing (mean) oscillation on the Bergman space of the unit ball. We show that the index calculation for Fredholm operators in this C∗-algebra can be easily and completely reduced to the classic case of Toeplitz operators with symbols that are continuous on the closed unit ball. Moreover, in addition to a number of other ...
متن کاملToeplitz Operators and Localization Operators
We show that for any localization operator on the Fock space with polynomial window, there exists a constant coefficient linear partial differential operator D such that the localization operator with symbol f coincides with the Toeplitz operator with symbol Df . An analogous result also holds in the context of Bergman spaces on bounded symmetric domains. This verifies a recent conjecture of Co...
