Localization operators on Bergman and Fock spaces
We introduce localization operators on weighted Bergman and Fock spaces and show that, under a natural scaling of symbols and window functions, localization operators on the weighted Bergman space $A_{βr^2}^2$ converge, in the weak sense, to localization operators on the Fock space $F_β^2$ as $r\to\infty$.

Arising of Bergman reproducing kernel in Bose-Fock space
Proyecciones (Antofagasta), 2018 We introduce a Bose-Fock space A (Dd) of anti-holomorphic complex-valued functions on the unit polydisc Dd in Cd, with d ? NU {?}.A unitary isomorphism U from the abstract Bose-Fock space ?H to A ( Dd) is produced, and it is shown that U transforms twisted coherent vectors into Bergman kernels in Dd.

Dual Toeplitz operators on the weighted Fock spaces
四川大学学报. 自然科学版With the successful characterization of the semi-commutativity of dual Toeplitz operators on the orthogonal complement of the Bergman space over the unit disk， dual Toeplitz operators on the orthogonal complement of analytic function spaces have ...

The extended eigenvalues of composition operator on Bergman space and Fock space
A complex scalar k is said to be an extended eigenvalue of a bounded linear operator A on a complex Hilbert space if there is a nonzero operator X such that AX=kXA. There are some solutions to the problem of computing the extended eigenvalues for composition operators induced on the Fock space and Bergman space by linear fractional transformationsof ...

We study whether essential positivity \[ σ_{\mathrm{ess}}(T_f)\subset [0,\infty) \] of a radial Toeplitz operator on Bergman and Fock spaces can be detected from the asymptotic behavior of its Berezin transform. For bounded real-valued radial symbols on $A^2(\mathbb{D})$, Perälä and Virtanen conjectured that \[ \liminf_{|z|\to 1^-} \widetilde{f}(z)\ge ...
