Abstract
Zero-one measure characterizations of lattice properties such as normality are
extended to more general measures. For a given measure, we consider two associated “outer”
measures and attempt to obtain the “outer”-measurable sets. We also seek necessary and sufficient
conditions for the measure and outer measures to be equal on the lattice or its complement.
