A class of Berezin-type operators on weighted Fock spaces with $A_{\infty}$-type weights
Let $0<\alpha,\beta,t<\infty$ and $\mu$ be a positive Borel measure on
$\mathbb{C}^n$. We consider the Berezin-type operator
$S^{t,\alpha,\beta}_{\mu}$ defined by
$$S^{t,\alpha,\beta}_{\mu}f(z):=\left(\int_{\mathbb{C}^n}e^{-\frac{\beta}{2}|z-u|^2}|f(u)|^te^{-\frac{\alpha
t}{2}|u|^2}d\mu(u)\right)^{1/t},\quad z\in\mathbb{C}^n.$$ We completely
characterize the boundedness and compactness of $S^{t,\alpha,\beta}_{\mu}$ from
the weighted Fock space $F^p_{\alpha,w}$ into the Lebesgue space $L^q(wdv)$ for
all possible indices, where $w$ is a weight on $\mathbb{C}^n$ that satisfies an
$A_{\infty}$-type condition. This solves an open problem raised by Zhou, Zhao
and Tang [Banach J. Math. Anal. 18 (2024), Paper No. 20]. As an application, we
obtain the description of the boundedness and compactness of Toeplitz-type
operators acting between weighted Fock spaces induced by $A_{\infty}$-type
weights.
