چکیده
We consider the so-called Berezin ?-sequence, where ? is an operator valued inner function, for operators on vector Hardy space H2E (D), and study invertibility of some model K? = ?H2E via ?-sequence. By applying symbols technique Toeplitz corona problem in Bergman L2a(D) studied. Moreover, C-invertibility C-unitarity are also defined

Toeplitz Operators with Bmo Symbols and the Berezin Transform
We prove that the boundedness and compactness of the Toeplitz operator on the Bergman space with a BMO 1 symbol is completely determined by the boundary behaviour of its Berezin transform. This result extends the known results in the cases when the symbol is either a positive L 1-function or an L ∞ function. 1. Introduction. Toeplitz operators are one of the most widely studied classes of concr...
متن کاملOn the Berezin - Toeplitz
I consider the problem of composing Berezin-Toeplitz operators on the Hilbert space of Gaussian square-integrable entire functions on complex n-space, C n. For several interesting algebras of functions on C n , we have T'T = T ' for all '; in the algebra, where T' is the Berezin-Toeplitz operator associated with ' and ' is a \twisted" associative product on the algebra of functions. On the othe...

My primary research interests are in the field of formal methods in computer-aided verification (or Formal Verification for short). This is a relatively young field in computer science which concerns with finding errors in hardware and computer programs, and proving correctness of such designs (absence of certain types of errors). Formal verification is often used in proving correctness of the ...
متن کامل1 Introduction Berezin-Töplitz Quantization
The general idea of quantization is to find a way to pass from the classical setting to the quantum one. In the classical situation, we have a symplectic manifold (M,ω) standing for the space of “states” of some physical system. The topological data of the manifold is contained in the structure of the function algebra C(M). The smooth structure on M gives rise to a distinguished subalgebra C∞ 0...
متن کاملBerezin Quantization of the Schrödinger Algebra
We examine the Schrödinger algebra in the framework of Berezin quantization. First, the Heisenberg-Weyl and sl(2) algebras are studied. Then the Berezin representation of the Schrödinger algebra is computed. In fact, the sl(2) piece of the Schrödinger algebra can be decoupled from the Heisenberg component. This is accomplished using a special realization of the sl(2) component that is built fro...
