Abstract
The lattice of z-ideals of the ring C(X) of real-valued continuous functions on a completely regular Hausdorff space X has been shown by Martinez and Zenk to be a complete Heyting algebra with certain properties. We show that these properties are due only to the fact that C(X) is an f-ring with bounded inversion. This we do by studying lattices of algebraic z-ideals of abstract f-rings with bounded inversion.
