    Let \(\phi\) be a subharmonic function for which \(\Delta \phi\) is a doubling measure. For each \(1 \leq p \leq \infty\), the generalized Fock spaces are defined as NEWLINE\[NEWLINE \begin{aligned} \mathcal{F}_{\phi}^{p} &= \bigg\{ f\;\text{is entire} \:\, \int_{\mathbb{C}}\! |f(z)|^p e^{-p\phi(z)}\frac{dm(z)}{(\rho(z))^2} <\infty \bigg\},\\ \mathcal{F}_{\phi}^{\infty} &= \bigg\{ f\;\text{is entire} \:\, \sup_{z \in \mathbb{C}} |f(z)| e^{-\phi(z)} <\infty \bigg\}, \end{aligned} NEWLINE\]NEWLINE where \(dm\) denotes Lebesgue measure on the complex plane \(\mathbb{C}\) and \(\rho(z)\) is the radius such that \((\Delta \phi)(D(z, \rho)) = 1\).NEWLINENEWLINEFollowing a scheme of Levin, the authors describe the values that the functions in \(\mathcal{F}_{\phi}^{p}\) (\(1\leq p<\infty\)) take on the lattices of critical density in terms of both the size of the values and a cancellation condition that involves discrete versions of the Cauchy and the Beurling-Ahlfors transforms.
