Some results for reproducing kernel Hilbert space operators via Berezin symbols

open access: yesFilomat
By applying the Berezin symbols method, we investigate the solvability of the Riccati operator equation XAX +XB-CX-D = 0 on the set of operators of the form Toeplitz + compact on the Bergman space L2a(D) of analytic functions in the unit disc D = {z ?C:|z|< 1}.

Use of reproducing kernels and Berezin symbols technique in some questions of operator theory

open access: yesForum Mathematicum, 2012
We give in terms of Berezin symbols some characterizations for the operators belonging to the Schatten-von Neumann classes sigma(p), 0 < p < +infinity, which were motivated by the questions posed by Nordgren and Rosenthal [7]. Some other problems related with the multiplicative equality for Berezin symbols are also discussed.

Berezin symbols and operator theory

open access: yes, 2000
Let 'H' be a standard analytic functional Hilbert space over a bounded domain [Omega] ? C. We examine the Berezin symbols 'A~' of bounded operators A?BH and characterize the compact operators KH by Berezin symbol behavior. We show that A?KH iff the Berezin symbol of every unitary conjugate of 'A' is in 'C'0([Omega]) (Nordgren and Rosenthal, 1994 ...

Berezin symbols of operators on the unit sphere of $\mathbb C^n$

open access: yes, 2017
We describe the symbolic calculus of operators on the unit sphere in the complex n-space $\mathbb C^n$ defined by the Berezin quantization. In particular, we derive a explicit formula for the composition of Berezin symbol and with that a noncommutative star product. In the way is necessary introduce a holomorphic spaces which admit a reproducing kernel
