Maximal zero sequences for Fock spaces

Abstract

A sequence $Z$ in the complex plane $\C$ is called a zero sequence for the Fock space $F^p_\alpha$ if there exists a function $f\in F^p_\alpha$, not identically zero, such that $Z$ is the zero set of $f$, counting multiplicities. We show that there exist zero sequences $Z$ for $F^p_\alpha$ with the following properties: (1) For any $a\in\C$ the sequence $Z\cup\{a\}$ is no longer a zero sequence for $F^p_\alpha$; (2) the space $I_Z$ consisting of all functions in $F^p_\alpha$ that vanish on $Z$ is one dimensional. These $Z$ are naturally called maximal zero sequences for $F^p_\alpha$.
