On Toeplitz operators between Fock spaces

Abstract

We study mapping properties of Toeplitz operators $T_{\mu }$ associated to nonnegative Borel measure $\mu$ on the complex space ${\mathbb{C}}^n$. We, in particular, describe the bounded and compact operators $T_{\mu }$ acting between Fock spaces in terms of the objects $t$-Berezin transforms, averaging functions, and averaging sequences of their inducing measures $\mu$. An asymptotic estimate for the norms of the operators has been also obtained. The results obtained extend a recent work of Z. Hu and X. Lv and fills the remaining gap when both the smallest and largest Banach--Fock spaces are taken into account.
