Toeplitz Operators on Weighted Bergman Spaces

Journal of Function Spaces and Applications, 2013
We characterize the boundedness and compactness of a Toeplitz-type operator on weighted Bergman spaces satisfying the Bekollé-Bonami condition in terms of the Berezin transform.

Design and Optimization of Finite Alphabet Waveforms for Multiple‐Antenna Radar Covariance Matching

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This article propose a novel method for finite‐alphabet waveform generation based on constrained matrix decomposition. It also expands theoretical feasibility bounds for generating covariance matrices with binary waveforms, proves that matrices from autoregressive processes are always realizable and introduces an optimal adjustment procedure for ...

Toeplitz Operator and Carleson Measure on Weighted Bloch Spaces

Journal of Function Spaces, 2019
In this paper, we consider Toeplitz operator acting on weighted Bloch spaces. Meanwhile, the inclusion map from weighted Bloch spaces into tent space is also investigated.

Hyponormality on a Weighted Bergman Space

Journal of Function Spaces, 2020
A bounded Hilbert space operator T is hyponormal if T∗T−TT∗ is a positive operator. We consider the hyponormality of Toeplitz operators on a weighted Bergman space.

The sharp upper bound for generation of linear semigroups by higher order equations with fractional powers

Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract In this paper, we consider a class of higher‐order equations and show a sharp upper bound on fractional powers of unbounded linear operators associated with higher‐order abstract equations in Hilbert spaces.

Combinatorics on number walls and the P(t)$P(t)$‐adic Littlewood conjecture

Mathematika, Volume 72, Issue 1, January 2026.
Abstract In 2004, de Mathan and Teulié stated the p$p$‐adic Littlewood conjecture (p$p$‐LC) in analogy with the classical Littlewood conjecture. Let Fq$\mathbb {F}_q$ be a finite field P(t)$P(t)$ be an irreducible polynomial with coefficients in Fq$\mathbb {F}_q$. This paper deals with the analogue of p$p$‐LC over the ring of formal Laurent series over

More subnormal Toeplitz operators.

Journal für die reine und angewandte Mathematik (Crelles Journal), 1986
In an earlier paper, J. J. Long and the author presented a subnormal Toeplitz operator that is neither normal nor analytic. It was constructed using the conformal map \(\psi\) of the disk onto the interior of the ellipse with vertices \(\pm i(1+\alpha)\) passing through \(\pm (1-\alpha)\) where ...

On some numerical characteristics of operators

Arab Journal of Mathematical Sciences, 2015
We investigate some numerical characteristics of Toeplitz operators including the numerical range, maximal numerical range and maximal Berezin set. Further, we establish an inequality for the Berezin number of an arbitrary operator on the Hardy–Hilbert ...
