* Any (measurable) subset of a null set is itself a null set (by <a href="page.php?w=Measure_%28mathematics%29">monotonicity</a> of ).</p>

<p>Together, these facts show that the null sets of  form a <a href="page.php?w=Sigma-ideal">?-ideal</a> of the <a href="page.php?w=sigma-algebra">?-algebra</a> . Accordingly, null sets may be interpreted as <a href="page.php?w=negligible_set">negligible set</a>s, yielding a measure-theoretic notion of "<a href="page.php?w=almost_everywhere">almost everywhere</a>".</p>
