TL;DR

This paper characterizes the compactness and boundedness of Toeplitz operators on weighted Bergman spaces with Békollé-Bonami type weights, extending understanding of their behavior in complex analysis and operator theory.

Contribution

It provides new characterizations of compact and bounded Toeplitz operators on weighted Bergman spaces for a broad class of weights, including radial and biholomorphic Jacobian weights.

Findings

Characterization of compact Toeplitz operators on weighted Bergman spaces.

Boundedness of Toeplitz operators for weights in a $u$-adapted class.

Weighted endpoint weak-type $(1,1)$ bounds established.

Abstract

We study the weighted compactness and boundedness properties of Toeplitz operators on the Bergman space with respect to B\'ekoll\`e-Bonami type weights. Let $T_u$ denote the Toeplitz operator on the (unweighted) Bergman space of the unit ball in $\mathbb{C}^n$ with symbol $u \in L^{\infty}$. We characterize the compact Toeplitz operators on the weighted Bergman space $\mathcal{A}^p_\sigma$ for all $\sigma$ in a subclass of the B\'ekoll\`e-Bonami class $B_p$ that includes radial weights and powers of the Jacobian of biholomorphic mappings. Concerning boundedness, we show that $T_u$ extends boundedly on $L^p_{\sigma}$ for $p \in (1,\infty)$ and weights $\sigma$ in a $u$-adapted class of weights containing $B_p$, and we establish analogous weighted endpoint weak-type $(1,1)$ bounds for weights beyond $B_1$.
